On Sunday, Robbie and her husband Ackerley, both 33, appeared together at Los Angeles' Shrine Auditorium and Expo Hall for the world premiere of the star’s new movieBarbie.

Robbie, who stars as Barbie herself in the comedy from filmmaker Greta Gerwig, dropped the film’s pink theme for its premiere as she arrived in a sparkling black gown complete with additional sleeved gloves and a diamond necklace, which appeared to match a Barbie doll’s costume from a 1960 Mattel toy.

Meanwhile, Ackerley — a producer on the film who has been married to Robbie since 2016 — matched his wife with a simple black tuxedo. Ackerley could be seen placing his hand around Robbie’s waist as the couple posed for photos together on Barbie’s appropriatelypink-colored red carpet.

The couple first met in 2013 on the set of the World War II dramaSuite Française; Ackerley worked as an assistant director on the film, while Robbie costarred with Michelle Williams and Kristin Scott Thomas. They began dating the following year andtied the knot in 2016.
