Emma Stone stole the spotlight in a stunning red dress at the Gangster Squad premiere in Los Angeles.
The 24-year-old actress picked a silk and brocade strapless Lanvin dress and matching red heels by Christian Louboutin when she walked the red carpet at the Grauman's Chinese Theatre in Hollywood.
She was joined by her leading men including a brown-suited Ryan Gosling - who brought his mum Donna as his date - Sean Penn, Josh Brolin and Giovanni Ribisi.
Ryan joked to E! News that his girlfriend Eva Mendes was there in spirit: "My mother's wearing all my girlfriend's clothes," to which Donna replied: "Yes, I'm wearing Eva Mendes. She let me raid her closet."
Emma, who plays actress Grace Faraday in Ruben Fleischer's stylish crime drama, joked that she's looking forward to teaming up with Ryan again following their previous collaboration on romantic comedy Crazy, Stupid Love.
She also revealed that the film set wasn't filled with too much testosterone.
"On the days I was there, it was mostly with Sean or Ryan. It wasn't too overwhelmingly testo fest - I was going to say something embarrassing about boys' privates - but it was fun," she said.
