Mary-Kate Olsen Bashes Spencer Pratt on Letterman

Mary-Kate Olsen made a creepy and uncomfortable appearance on David Letterman last night to promote her new film The Wackness. Mary-Kate talked about spending her 22nd birthday at Bonnaroo, making out with Ben Kinglsey, and not wanting her kids to be child actors. Then she talked about Spencer Pratt, who Mary-Kate said she went to high school with. Dave mentioned Spencer is a little "wormy," and "oily."

Mary-Kate: He does not have a good temper. He walked out of a few games. He would walk off the field. He was like, ’Me or the coach!’

Dave: Were you friends with the guy at the time?

Mary-Kate: No.

Dave: Because I’m surprised about the soccer. Because looking at the guy, he looks like a guy that has never broken a sweat, I would guess.

Mary-Kate: Oh, my God - that brings up stories! I don’t know if I should talk about it.

Dave: No, c’mon, let’s hear one. Let’s go.

Mary-Kate: [laughs] The Wackness is a great film.

Dave: What I don’t understand is how does a kid that age, and he’s only in his 20s or maybe even your age, how does a kid like that get to be so oily?

Mary-Kate: It’s a mystery to me.

Dave got a little tickle fantasizing about Mary-Kate making out with a guy his age.
