Diane Kruger had the perfect accessory for her look at the Metropolitan Museum of Art’s Costume Institute Gala on Monday.
She sported a large square-cut diamond on her ring finger, along with another sparkling wraparound ring.
Kruger’s rings complemented a neon green party dress with a cutout over her stomach, a puffy skirt and a cape with a long train. She finished the ensemble with a pair of hot pink pumps with jeweled straps and some multi-colored statement earrings, which brought out her pink eyeshadow.
Reedus, 52, began dating the actress after they met on the set of their 2015 movie Sky. They went public with their relationship in March 2017 when they were spotted getting cozy in the streets of New York City.
The couple’s first pregnancy was confirmed by PEOPLE in May 2018, and they welcomed their daughter, now age 2½, that November. Reedus also shares son Mingus Lucien, 21, with ex Helena Christensen, 52.
“She’s not really girlie, she’s kind of a dude,” Kruger told PEOPLE of their daughter in April 2019, adding that she’s still saving some Chanel for her kid. “It’s fun to have a girl, I will say. I like that, too.”

The Costume Institute Gala at the Metropolitan Museum of Art was delayed from its usual scheduled date on the first Monday in May after last year’s event was cancelled due to the COVID-19 pandemic.
