Bradley Cooper admits he's pretty chummy with Cameron Diaz, who has been on the actor's arm around New York the past month.

"I think she's great," Cooper told PEOPLE at Saturday's Nip/Tuck season 5 premiere in Hollywood. "We're good friends."

Cooper, 32, and Diaz, 35, were photographed on the sidelines of Sept. 30's Giants-Eagles NFL game alongside Ashton Kutcher (Diaz's What Happens in Vegas ... costar) and Demi Moore. The two also looked cozy during a recent stroll through Central Park and during a Saturday Night Live afterparty.

Cooper, who split with wife of four months Jennifer Esposito in May, appears next in 2008's He's Just Not That into You, opposite Jennifer Aniston and Drew Barrymore.

Of his burgeoning movie career, Cooper told PEOPLE, "I'm sort of nomadic. I love going on location. The 9-to-5 aspect, and the no-end-in-sight aspect of TV, is not exactly in tune with what I like to do." – Nicholas White
