Ryan Gosling and Emma Stone came together last night at Grauman's Chinese Theater in Hollywood for the World Premiere of their film "Gangster Squad". It's the second time the co-stars have played love interests on the big screen. They also appeared in 2011's "Crazy, Stupid, Love"

Stone, who plays a moll in the film, dazzled in a fiery red Lanvin woven silk dress complemented with a dramatic crystal necklace.

Ryan Gosling, wearing a brown, three-piece Gucci suit, brought a very special woman to the event, his Mom Donna. Gosling's girlfriend, actress Eva Mendes, did not attend the premiere, but her clothes did. "My mother's wearing all my girlfriend's clothes," Gosling told reporters, according to the New York Daily News. "I'm wearing Eva Mendes tonight" Donna Gosling added. "I raided her closet."

Strangely, the most daring bit of attire at the event came from Nick Nolte who was sporting, what looked like, a yellow bathrobe as he made his way down the press line.

Also on hand were Sean Penn, Anthony Mackie, Giovanni Ribisi, Robert Patrick and Josh Brolin, who also have roles in the film, due for release on Wednesday January 9, 2013. (photos © 2013 Joe Martinez/ Picturelux - All Rights Reserved.)

About the film:

Los Angeles, 1949. Ruthless, Brooklyn-born mob king Mickey Cohen (Sean Penn) runs the show in this town, reaping the ill-gotten gains from the drugs, the guns, the prostitutes and—if he has his way—every wire bet placed west of Chicago. And he does it all with the protection of not only his own paid goons, but also the police and the politicians who are under his thumb. It’s enough to intimidate even the bravest, street-hardened cop…except, perhaps, for the small, secret crew of LAPD outsiders led by Sgt. John O’Mara (Josh Brolin) and Jerry Wooters (Ryan Gosling), who come together to try to tear Cohen’s world apart.
