At 24 years old -- the same age as Lindsay Lohan -- former child actress Mary-Kate Olsen seems to have her rocky years behind her.

Stars of Full House from infancy, Mary-Kate and her twin sister Ashley went on to become mini-moguls with TV, film and merchandising enterprises that made them multi-millionaires in their tweens. The sisters now have their own fashion lines incuding Elizabeth and James, The Row plus JCPenney's Olsenboye.

And although she continues to act (she has a role in the 2011 Vanessa Hudgens horror flick Beastly), she tells Marie Claire mag that she can't relate to her past as a "little monkey performer."

"I look at old photos of me, and I don't feel connected to them at all," she tells the magazine. "I would never wish my upbringing on anyone...but I wouldn't take it back for the world."

The petite star famously battled an eating disorder, entering a facility in 2004, and her friendship with Heath Ledger at the time of his 2008 overdose death was closely scrutinized.

Declining to discuss those well-known headlines in detail, she tells Marie Claire simply: "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."

Her biggest support system? Her sister. "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."
