Hollywood hunk Bradley Cooper and his much-younger girlfriend, Suki Waterhouse, made their first public appearance together at the “American Hustle” world premiere at the Ziegfeld Theater in New York City on Sunday, according to Us Weekly. Cooper, 38, and Waterhouse, 21, are typically pretty private about their relationship, but over the weekend they were seen noshing on chocolate-covered strawberries. Waterhouse, however, didn’t appear with Cooper for red carpet photographs.

The couple coordinated their outfits for the Hollywood event. The former “Sexiest Man Alive” wore a grey suit and his gal pal donned a chic grey turtleneck, though it looked like the British Burberry model wasn’t wearing a bra. The Philadelphia native reportedly sat with his “American Hustle” co-stars at the after-party held at Cipriani.

"Guests were greeted with cocktails before entering the massive space, which was decked out '70s style complete with sparkling disco balls," a source told Us Weekly about the party, which was presented by Grey Goose and Vanity Fair. "Cooper posed with fans for photos, and later caught up over dinner [with Waterhouse.]"

The couple has been together for nine months, but they waited until this past weekend to make their first Hollywood appearance together. It was intentional, apparently. When the 21-year-old told Elle UK in January that she didn’t like talking about her boyfriend. "I don't talk about my boyfriend because it's boring. At least, that's what I decided to tell you when you asked," she said.

"I do think whatever I say will sound weird. But the truth is, if I start talking about him, I probably won't be able to stop. And I don't really want to talk about him, you know?"

Just months after Cooper and his ex-fiancé, “Avatar” star Zoe Saldana, broke up, the actor was spotted with Waterhouse in March in Boston after they reportedly met at the Elle Style Awards in February. But chances are that the actress doesn’t have any hard feelings; she secretly wed Italian artist Marco Perego in July.
