In another case of celebrity TMI, Amanda Peet has admitted in next month's issue of In Style that she and husband, David Benioff, like to spice things up... in the bathroom. "My husband and I were recently watching an episode of Seinfeld where Elaine says, 'You can't have sex in a bathtub, that's impossible,'" relates Amanda. "And we just looked at each other. No, it isn't impossible. It's sort of slippery, yes. But fun." And it seems like Amanda isn't too much of the jealous type. "David used to have an outdoor stereo by the pool at his bachelor pad... I'm sure he lured many women there, but I was the last one."
