The 21-year-old model turned actress posed for some pictures with Fawaz Gruosi, who is the head of De Grisogono — the designer of the gorgeous backlace she wore just the night before.
Just before walking the carpet, Cara was spotted hanging out with pal Lily Allen by the sea before making an appearance on Le Grand Journal.
“#regram @chastainiac you MEGA babe! Had so much fun on Le grand journal with these gorgeous ladies #MarionCotillard #legrandjournal #Cannes #BOOM,” Cara captioned on Instagram.
FYI: Cara is in head-to-toe Chanel for the premiere and is wearing Levi’s shorts while hanging with Lily.
