Cameron Diaz didn't mind Justin Timberlake sex scene

(Bang Showbiz)

Cameron Diaz would have found her 'Bad Teacher' sex scene awkward if it was with anyone other than Justin Timberlake.

The former couple - who dated for almost four years until December 2006 - star together in the comedy movie in which the actress' character Elizabeth Halsey romantically pursues Justin's alter-ego Scott Delacorte, and the blonde beauty admits she wouldn't have been so comfortable with anyone else.

She said: "If it was anyone else it would have been awkward. It would have been a different scene. But instead we laughed a lot. And because it was him, it just wasn't uncomfortable.

"We were able to do things I may not have been comfortable doing with somebody else. There is so much trust there, there is no issue.

"Justin and I know who we are and we know where we stand in our relationship. So there's a comfort in that and a safety."

Justin also recently insisted he didn't find shooting intimate scenes with his ex-girlfriend uncomfortable.

Asked if it was awkward because of their relationship history, Justin said: "I didn't look at it like that. We obviously know each other, but I looked at it as a really funny, funny scene that I've never seen done before.

"What I actually remember was, you know, they got to my close-up for that scene, so I was just kind of by myself - which is hard to imitate in real life."
