The Oscar nominee set the bar quite high with her look for the festival’s opening ceremony: a strapless, silver Jacquemus gown featuring a mermaid skirt paired with a diamond statement necklace.

Demi and Brad’s fashionable relationship sparked when they met in 2008 and solidified when he styled her for the first time in 2011. 

“I know that I have the safety of somebody who looks out for me,” Demi raved to Women’s Wear Daily in January, “who truly is looking out for what’s in my best interest.”

And leaning into the world of fashion has helped Demi—who shares daughters Rumer Willis, 37, Scout LaRue Willis, 34, and Tallulah Willis, 32, with ex-husband Bruce Willis—acknowledge and feel more comfortable with the different aspects of her personality.

“What I’ve learned is you don’t have to try too hard to be unique,” she explained. “Sometimes I’m looking like this, and I go, ‘Oh, is that real when I’m in these other things?’ And I realize, yes, they’re all me. They’re just aspects of me. And how lucky am I that I get to play in that arena? That I get to step into a world that has fantasy?”
