Celebrity siblings: They’re just like us—or at least they started out that way. Yes, these famous duos (and one trio) grew up sharing bunk beds and bathrooms, and now they share the Hollywood spotlight, whether fans realize the familial connection or not. From a Gossip Girl and a Teen Witch to two iconic Hollywood legends who happen to share parents, here are the surprising celebrities you’d never guess were actually siblings. 1 Blake and Robyn Lively Long before Blake Lively ever landed her starring role on the teen drama Gossip Girl, her older half-sister, Robyn Lively, had a thriving acting career of her own. Back in the day, she starred in the cult classic film Teen Witch and even had a major role on the hit show Twin Peaks. In an interview with Access Hollywood in 2017, the sisters sweetly shared that they are “best friends” and that their bond is “everything,” despite their 15-year age gap.They also have three more siblings: Robyn’s sister and Blake’s half-sister, Lori; Robyn’s brother and Blake’s half-brother, Jason; and Blake’s brother and Robyn’s half-brother, Eric. (Lori is the oldest and Blake is the youngest of the crew.) All five share the same mother, talent agent Elaine Lively, and all five have worked in the entertainment industry.

Captain America, in the Marvel Cinematic Universe. And his brother, Scott Evans, is probably best known from his seasons playing Oliver on the soap opera One Life to Live. If you follow either of the Evans boys on Instagram, you know that they have a pretty typical sibling relationship, including an ongoing prank war in which they jump out and scare each other. Complex, mature stuff! 3 Debbie Allen and Phylicia Rashad In the mid-’80s and early ’90s, Phylicia Rashad famously starred on The Cosby Show as the family’s beloved matriarch, Clair Huxtable. Rashad has an equally talented younger sister in dancer and choreographer Debbie Allen. In fact, Allen began her legendary run on the hit series Fame in 1982, before The Cosby Show even premiered. At the time, the connection was fairly well known. But these days, with Allen’s younger fanbase courtesy of Grey’s Anatomy, many millennials and Gen Z-ers are surprised to learn of the family ties between the two. 4 Florence Pugh and Toby Sebastian Florence Pugh has had a huge past few years, with acclaimed roles in Midsommar, Little Women, and her upcoming MCU debut in Black Widow. Because they work under different names, you likely missed that her brother Toby Sebastian is also an actor. Most notably, he played Trystane Martell on the fifth season of Game of Thrones and opera singer Andrea Bocelli in the 2017 biopic, The Music of Silence.For more celebrity news sent right to your inbox, sign up for our daily newsletter. 5 Warren Beatty and Shirley MacLaine Shirley MacLaine (born Shirley MacLean Beaty) got her start in Alfred Hitchcock’s 1955 film The Trouble With Harry. Just two years later, her brother Warren Beatty (born Henry Warren Beaty) made his debut on the small screen on Kraft Television Theater, which ultimately lead to a legendary film career.To this day, many don’t realize that MacLaine and Beatty are siblings, as both chose to alter their birth names when they got their big break. However, as MacLaine shared with Vanity Fair in 2017, the two are still close. “I’m three years older, and I’m protective,” said the actor. 6 Lily and Alfie Allen In 2006, British pop star Lily Allen released a song called “Alfie,” playfully imploring her lazy younger brother to straighten out his life and get a job. So though they may not realize it, Game of Thrones fans might have this song to thank for one of the show’s most noteworthy characters. Lily’s little brother, Alfie Allen, joined the hit HBO series as Theon Greyjoy in 2011. He even earned an Emmy nomination for his performance in 2019. Thanks, sis! 7 Dennis and Randy Quaid Brothers Dennis Quaid and Randy Quaid have many things in common: parents, a love of acting, and myriad of public struggles. Younger brother Dennis’s career took off in the ’80s thanks to roles in Innerspace, The Big Easy, and Great Balls of Fire! But in the ’90s, he struggled with substance use disorder, an eating disorder, and eventually a messy divorce from America’s sweetheart, Meg Ryan. Older brother Randy, meanwhile, made a name for himself in the ’70s and ’80s—even earning an Oscar nomination for The Last Detail in 1973 and gaining a massive fanbase as Cousin Eddie in the National Lampoon’s Vacation movies. But recently, he’s gotten into quite a bit of trouble with the law. 8 Chris, Liam, and Luke Hemsworth Brothers Chris Hemsworth (Thor) and Liam Hemsworth (The Hunger Games) are known all over the world for their dashing good looks and acting prowess. But all too often, people overlook the third Hemsworth brother Luke, who plays Ashley Stubbs on HBO’s sci-fi drama Westworld. The more Hemsworths, the merrier!RELATED: 100 Celebrities You Won’t Believe Are The Same Age. 9 Jonah Hill and Beanie Feldstein In recent years, Jonah Hill has shown the world that he is able to tackle any genre, moving on from raucous teen comedies like Superbad to more serious films like the Oscar-nominated baseball flick Moneyball. And given Hill’s success as both an actor and director, it should come as no surprise that talent runs in his family. Hill’s younger sister, Beanie Feldstein, earned accolades for her performance in 2019’s hilarious coming-of-age dramedy Booksmart, and she also appeared in Greta Gerwig’s Oscar-nominated film Ladybird in 2018.If you weren’t aware that Hill and Feldstein were related, don’t feel bad: Though Hill’s last name is legally Feldstein (Hill is his middle name), only his sister still uses the family name professionally. Despite the differing monikers, these two have such a special sibling bond that Hill got a “Hello, Beanie!” tattoo in 2018, in honor of his sister’s performance in the 2017 Broadway revival of Hello, Dolly! 10 Kate and Oliver Hudson Almost Famous star Kate Hudson and Rules of Engagement star Oliver Hudson, are—unbeknownst to many—both the children of Goldie Hawn and Bill Hudson. After a messy divorce, the siblings were raised by Hawn and stepfather Kurt Russell, and were later very publicly disowned by their biological dad. The duo now work together under the banner of Kate’s activewear brand Fabletics, with her big brother Oliver spearheading the men’s division, FL2. 11 Charlie Sheen and Emilio Estevez Don’t let their differing surnames confuse you: Charlie Sheen and Emilio Estevez are brothers. Their father, West Wing star Martin Sheen, was born Ramón Estevez, but changed his name when he started working. While all four of Martin and Janet Sheen’s children were given the last name Estevez on their birth certificates, younger brother Charlie chose to follow in his father’s footsteps and embrace the “Sheen” stage name when he got his big break. Emilio, meanwhile, stuck with his birth name in hopes of blazing his own trail in the acting world. 12 Cuba Gooding, Jr. and Omar Gooding The sons of two entertainers, Cuba Gooding, Jr. (Jerry Maguire) and Omar Gooding (Hangin’ With Mr. Cooper) were always encouraged to pursue their passion for acting. Older brother Cuba, Jr. was the first who decided to follow his Hollywood dreams, taking classes and signing with an agent in the early ’80s. His younger brother Omar was later discovered by talent scouts while dropping off a script for Cuba, Jr. Omar went on to host the Nickelodeon game show Wild&Crazy Kids and to star on family sitcoms like Hangin’ with Mr. Cooper and Smart Guy in the ’90s. 13 Jesse and Hallie Eisenberg Jesse Eisenberg is best known for his Oscar-nominated performance as Mark Zuckerberg in the 2010 film The Social Network. However, long before his big break, his little sister, Hallie Eisenberg, was winning over the public in the 1998 movie Paulie and as “the Pepsi Girl.” Yes, that adorable, curly-haired spokesgirl who would crack open a refreshing Pepsi in the brand’s late ’90s and early ’00s commercials paved the way for her big brother. She hasn’t done much acting over the past decade, but it’s nice of her to give the elder Eisenberg the chance to shine. 14 Rooney and Kate Mara We know Rooney Mara as the vigilante computer hacker Lisbeth Salander from the film adaptation of Stieg Larsson’s novel, The Girl With the Dragon Tattoo, and for walking red carpets with her equally talented partner, Joaquin Phoenix. Her sister Kate Mara is equally recognizable, having famously played reporter Zoe Barnes in the first season of the Netflix political thriller House of Cards. However, what many fans of these powerful actors likely don’t realize is that Rooney is Kate’s younger sister. What’s even more surprising than their sibling connection? These women are football royalty: Their mother’s family (the Rooneys) owns the Pittsburgh Steelers and their father’s family (the Maras) owns the New York Giants. 15 Jason and Justine Bateman It’s easy to forget that Jason Bateman and his older sister Justine Bateman have been in the limelight for almost four decades. In the ’80s, Jason started his career on Little House on the Prairie and Silver Spoons, while Justine got her big break on Family Ties. Since then, Jason has starred in hit shows like Arrested Development and Ozark, and Justine has appeared on series like Desperate Housewives and Californication. She also made a cameo on Arrested Development in 2006—and the episode was full of in-jokes for anyone who knew about this sibling pair. 16 Fred and Ben Savage Fred Savage and Ben Savage each starred in a highly revered coming-of-age television series: The Wonder Years and Boy Meets World, respectively. The shows even overlapped for a bit in the early ’90s—and though this could have easily been cause for jealousy or competition, the brothers shared with E! News in 2015 that they were each glad to have someone else in the house who understood what they were going through. After all, not everyone grows up in the spotlight with the whole world watching. 17 Ariel Winter and Jimmy Workman Ariel Winter is best known for playing middle sister Alex Dunphy on the popular ABC sitcom Modern Family. But in real life, Winter is the youngest of three, with an older sister and an older brother. What fans might not realize, though, is that they might already know her brother: His name is Jimmy Workman, and he played Pugsley in The Addams Family and Addams Family Values in the ’90s. Winter’s family dramas have been media fodder for years, and as People reports, she and her brother are currently estranged, ever since Workman sided with their mother when she denied Winter’s abuse allegations. 18 Zooey and Emily Deschanel Sure, their shared last name and piercing blue eyes have probably tipped a few people off, but you still may not have realized that Emily Deschanel and Zooey Deschanel are sisters. Emily is most famous for starring as the titular character on the Fox series Bones from 2005 through 2017, and Zooey is an actor, singer, and songwriter. She’s best known for starring on the Fox comedy New Girl, in the 2009 movie 500 Days of Summer, and for being one half of the musical duo She&Him. 19 Kevin and Nora Dunn Nora Dunn got her start on Saturday Night Live in 1985, and to this day, she’s best known for her work on the sketch comedy show. A few years after Nora started on SNL, her brother Kevin Dunn began his own acting career, making appearances on some of the most popular shows of the ’80s and ’90s—Cheers, 21 Jump Street, Roseanne, and Seinfeld, to name a few. Most recently, Kevin starred on Veep as former White House Chief of Staff Ben Cafferty. The comedy gene clearly runs in the family. 20 Liev and Pablo Schreiber Though they share a last name, you may not have connected Ray Donovan star Liev Schreiber to American Gods and Orange Is the New Black actor Pablo Schreiber. They’re half brothers who have the same father: Tell Carroll Schreiber, who was also an actor. With 10 years between them, the two didn’t grow up at the same time, but they’ve supported each other’s careers and even worked together in one film: the 2004 remake of The Manchurian Candidate.RELATED: 50 Celebrities Whose Real Names You Never Knew.
