I’m particularly excited to see MK on Conan on Halloween! Her interviews on his show are always so great.

I thought Mary-Kate Olsen looked gorgeous when she appeared on David Letterman last night. She did a great job on the show and you can watch the video here.

I love her dress, but am not the biggest fan of the sunglasses. But they’re very MK, aren’t they!!

One more photos, sans glasses, after the jump!

Mary-Kate Olsen was a guest on David Letterman last night. She was fantastic. I love the song choice they made for her entrance. She seemed a lot more comfortable than she did at Conan O’Brien.

She talks about being on Full House, celebrating her birthday at Bonaroo with Ashley and eight of her friends, being on Samantha Who?, The Wackness, making out with Ben Kingsley, how she knew Spencer Pratt as a teenager, and more.

It’s a little annoying how David keeps interrupting her, but he’s pretty funny, so I’ll let it slide.

Mary-Kate Olsen will be a guest on The Late Show With David Letterman tomorrow. She’ll talk about The Wackness (which premieres tonight in NYC), her and Ashley’s upcoming book Influence and whatever else David throws her way.
