"And I don't understand the point of people looking for bad things," Barton, 23, goes on. "Why bother? I know it's human nature to want to pick on other people, but I find it a little shallow."

Barton tells the magazine she went from a size 12 to a size 6 or 8 after breaking up with Rooney guitarist Taylor Locke last September.

"The only way to be happy and be a more enjoyable person to be around is to embrace what you've got," she says. "Everyone has issues about their body, but I feel confident now. I'm healthy and happy."

But that doesn't mean Barton -- who was recently cast in the CW show A Beautiful Life -- is without flaws.

"I think people see celebs as having these perfect lives," she says. "But that's not true."

"Instead, what counts is that the people in your life your family and friends think you're a nice person," she continues.
