Mary Kate Olsen

Mary Kate Olsen has moved on from dating the actor types and is now giving a designer a shot.

She’s started dating Upper Echelon Shoes co-founder Seth Campbell. The relationship is fairly new and the two don’t even know if they like each other but the news of them dating is already public so might as well go for it.

A source told Us Weekly: "Their relationship is fairly new. They've been able to have a few dates on the down low. He's a downtown kind of guy, likes to party every now and then.

"His company is in the press but he's not, so it works out that way. They're both like each other and are just seeing where things go. Having fun."

Mary Kate must like him if she took him to her sister Elizabeth’s birthday in NYC.

Mary Kate has always had interesting taste in men. She’s dated Greek shipping heir Stavros Niarchos, then was linked to Heath Ledger and recently she was dating some artist. Let’s see how this designer boy works out.

Mary Kate Olsen grew up in the limelight with everyone watching her every move. And now that she’s all grown up, the twin to Ashley is looking back on how she made it through being a child in Hollywood.

In a new interview with Marie Claire, MK says she can’t even relate to her past at this point.

"I look at old photos of me, and I don't feel connected to them at all,” she explains. As for growing up in the limelight, Mary Kate says, I would never wish my upbringing on anyone…"

“But,” she adds quickly, “I wouldn't take it back for the world."

She went through a rough period of time a couple years back, battling an eating disorder and getting treatment in 2004. But the worst time was the death of close friend Heath Ledger.

Mary Kate tells the mag, "I think it's really important to be able to talk when something's wrong. I learned at a really young age that if you don't talk about it, it can drive you insane."

Nowadays, MK is still acting a little bit, but is more focused on her fashion lines she owns with her twin sister, Elizabeth and James, The Row and now Olsenboye for JCPenney.

"It took us a year-and-a-half to make the first T-shirt," she says. "I still read scripts, and if something great comes along, that's great … but this is my day job. The Row is where I go every day."

And one thing that hasn’t changed is her relationship with Ashley. "Sometimes Ash and I have to bring each other back, or push each other more," she says. "It's really helpful to have another half; we're constantly checking in with each other."

We love that Mary Kate has grown up so much! She made it through the rough years, and has gone on to be so successful! What an inspiration!
