"Gossip Girl" star Chace Crawford does not want his grandparents watching him have sex on a barstool!

Chace Crawford says he can sometimes get uncomfortable with the racy undertone of his CW hit Gossip Girl.
"Is that a weight on my conscience?" Crawford says in a new interview with London's The Independent. "Well, yes, I think it is. I come from a moral background, and I can see the power of the show, and imagine my old school teachers cringing, or my grandparents thinking, 'Oh, my God,' when they see me, say, having sex on a barstool. But you have to remember, this is not a reality show. It's supposed to be pure entertainment."
