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.

Mary-Kate Olsen was partying at Foxtail in Los Angeles last night, and she got really drunk, so drunk she actually fell down backwards as she tried to get in her waiting car. She even had to have someone help her up.

Mary-Kate Olsen and Ben Kingsley made a movie together called The Wackness. This movie looks like a straight to DVD. Why isn’t Kinglsley doing award winning movies? Maybe he’s just bored. Maybe he should try appearing in some high school plays while he’s experimenting. I’m sure they’d be happy to have Mary-Kate in those too.

Hugh Hefner has tried to get Mary-Kate and Ashley Olsen to take their clothes off for Playboy before, but they rejected his offer. Now he’s trying again. The Olsen girls are worth $1 billion dollars these days due to their success in the fashion industry, so it’s hard to imagine they’d pose for Playboy unless they really crazed attention. The girls have said no again to Hefner’s offer. It’s not really bad news though. I for one am not sure if I’m ready to see the skeletons underneath those bizarre, but expensive, clothes.

Kirsten Dunst has checked into the Cirque Lodge in Utah, according to Star magazine:

"She desperately needed help," a source in Utah tells Star. "She seemed to be intoxicated when she checked in because she was acting really erratic. She was extremely emotional, constantly breaking down in tears. She not in a good place right now, but thankfully, she’s getting the help she needs."

Eva Mendes is also being treated at Cirque. Past celebrity patiens include Lindsay Lohan, Richie Sambora, and Mary-Kate Olsen. Kirsten is being treated for alcohol, and substance abuse addictions.
