The former Full House star is all grown up! Seriously, can you believe she's 24 already? The same age as LiLo!

MK talks to Marie Claire about her busy life as a movie actress, fashion designer (from The Row to Olsenboye with sister Ash) and, of course, a celebrity.

"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," says Mary-Kate. "Sometimes Ash and I have to bring each other back, or push each other more. It's really helpful to have another half; we're constantly checking in with each other."

But MK also claims that she would "never wish my upbringing on anyone... but I wouldn't take it back for the world."

As for old photos of MK? "I don't feel connected to them at all," she says. I dunno about old pix, but this one above is as sexy as ever!
