Mila Kunis graced the cover of Harper's Bazaar April issue.

Wearing Alexander McQueen, Chanel, Dolce & Gabanna, and Christian Dior.

To play a ballerina in her 2012 movie "Black Swan," Kunis lost 20 pounds from her already lean shape, until "I was muscles, like a little brick house, but skin and bones," according to the actress.
And the tragedy didn't end there.
When she started to gain weight, "all the weight that left my chest went to my side hip, my stomach."
Drastic weight loss can result in a subsequent weight gain, and what comes back is not the muscle you lose but fat, a dietitian told MSNBC.
"Some people store fat in their bellies, others in their thighs or their breasts or their buttocks," said Andrea N. Giancoli, a registered dietitian and spokeswoman for the Academy of Nutrition and Dietetics. "Wherever you typically store fat, you're going to see it go back there."

But now it's good to see Kunis back in healthy shape.

The 28-year old told the magazine that she works out with a trainer a few times a week.
