Baldwin refused to bare his butt

The 30 Rock star plays Meryl Streep’s love interest in the comedy and strips off for one scene in which he tries to seduce Streep’s character.

But director Nancy Meyers reveals the bum in the film isn’t really Baldwin’s – because he didn’t want to shed his pants.

Meyers tells USA Today, “He said, ‘Mine’s beautiful. However, I don’t want to do that.'”
