'Gossip Girl' Blake Lively, 22, gets naked with Alan Arkin, 75? Only in Hollywood

"Gossip Girl" star Blake Lively talks sleeping with a much older man -- Alan Arkin -- in her new Oscar-buzzed film, "The Private Lives of Pippa Lee."

At the L.A. junket, she admitted it seemed weird when she first read the script. But then she realized that young Pippa is not looking for a sexual partner. She's looking for Daddy.

"It's not lust that attracts her to him. It's that she doesn't have a parent. It's him fulfilling that hole of a parent. He's the first person that guides her, and that provides her security and comfort, so that's what their relationship was about. So, we weren't busy trying to fabricate sexual chemistry."

OK, and  the naked bed scene?

She admits that anytime one is in strategically placed clothes taped on your body, in front of some strangers., there's a discomfort factor.

"But, I was with Alan and Rebecca, and our wonderful D.P., and it was a very private set. We're all actors, we're all professionals and we all understood what was happening. Everybody is uncomfortable with those scenes. You're never going to be comfortable being half-naked in front of anyone. But, it was fine. It was a short scene. For me, it's more uncomfortable to watch it. It's like, "Oh, no, all these people are seeing me like this!"

We bet lots of people will watch Pippa Lee just for those scenes. Especially 75-year-old men.
