X17 Online spotted Mary-Kate Olsen in Brentwood outside Fantastic Sam’s with a pal on Saturday afternoon.

MK was also seen on September 16 at LAX airport, talking on her cell phone and smoking as she waited for her bags in her car.

See the photos here.

Last night, MK seemed to be in high spirits as she waited for her car outside Toscana restaurant last night after dining there with a few friends. She even smiled at the paparazzi and flashed them a peace sign as she took off.

Does anyone watch Project Runway? I do, and I love it! This week, the designers were told that they were going to design for a fashion legend and tanning-addicted Blayne really wanted this fashion legend to be Mary-Kate Olsen.

Here’s Joel McHale from The Soup making fun of Blayne for his comments:

I’m not a big fan of Blayne, but I really don’t mind him. The designers this season have, for the most part, been whiny and annoying. Kenley used to be my favorite, but now Terri and Korto are.

What about you?

Also, this really, really, really made me want MK or Ashley to make an appearance on Project Runway. If Diane Von Furstenburg can, why can’t they?

Ashley Olsen was seen leaving Orso, a trendy restaurant in LA, last night with Justin Bartha and pal Estee Stanley (who looks very pregnant!) and her husband. Ashley was wearing a fedora and hid her face from the cameras the entire time.

I love Ashley, but wouldn’t life be easier if she just didn’t hide from the paparazzi? They’re taking photos anyway. But then again, I’m not a celebrity and will never understand what it’s like to have cameras in my face 24/7.

If you were a celebrity, how would you deal with paparazzi?

Mary-Kate Olsen is going to be on the cover of the next issue of UK Elle. To tease us, Elle has posted this behind-the-scenes video of her cover shoot!

I love how the creative director admits everyone is “vaguely obsessed with her.” The shoot looks really interesting–I’m excited to see the final product!

The magazine should hit newsstands soon.

Mary-Kate Olsen is only in The Wackness for nine minutes. She’s featured in two scenes and in both scenes, her character, Union, is stoned out of her mind. I think MK did a great job in her role, but I think it’s weird that the media and the studio hyped her perfomance in the film so much and she’s in it so little.

The video below is her first scene in the film. It’s early in the movie and Stephanie, Luke’s love interest, just found out that Luke is a dealer. MK is one of his regular clients.

The video below is her second, and final, scene in the film. This scene is much longer and it’s the infamous bar scene wherein she makes out with Ben Kingsley’s character.

What do you think of Mary-Kate’s performance? What sort of role do you think she should take on next?

X17 Online spotted Mary-Kate Olsen going into Maxfield on Wednesday afternoon. She ignored the cameras as she headed inside the store. There’s not much to the video, but we haven’t seen many candids of either girls lately, so I thought I’d share.

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.

This is a music video for the song “The Olsen Twins Song.” The premise of the video (and the song!) is that this “normal” dude spent a week in Vegas with the girls and they did all the vulgar and inane things one is supposed to do when one is in Vegas–sex, drugs, rock and roll.

I’ll admit, I got the chorus (I spent a week in Vegas with the Olsen Twins…) stuck in my head for a bit. Not cool!

Here is the third trailer for Mary-Kate Olsen’s new movie The Wackness. This trailer focuses on the relationship between Luke, played by Josh Peck, and Stephanie, played by Olivia Thrilby. Mary-Kate isn’t in the trailer at all.

Here’s a video of Mary-Kate and Ashley Olsen working the red carpet at the MET Costume Institute Gala on Monday night. The girls look like they are enjoying themselves, which is great to see!

All the flashes and yelling is crazy! The red carpet would be so overwhelming!
