Los Angeles: Hollywood star Bradley Cooper and girlfriend Suki Waterhouse made their first public appearance at the `American Hustle` world premiere party.
Cooper, 38, and Waterhouse coordinated their outfits, with the actor wearing a gray suit and black tie, while Waterhouse kept it simple and chic in a gray turtleneck, reported E! online.
Cooper, who plays FBI agent Richie DiMaso in `American Hustle`, sported a new haircut which he has in the movie.
The 21-year-old model had recently said that she does not like to talk about her boyfriend.
"I`m not one of those girls who go on about their boyfriends. I do think whatever I say will sound weird. But the truth is, if it starts talking about him, I probably won`t be able to stop. And I don`t really want to talk about him, you know," she had said.
