It's hard to believe the Silver Linings Playbook star is just 22!

"There's that Kate Moss quote that's like, 'Nothing tastes as good as skinny feels,'" said Lawrence, who put her signature curves on full display that year. "I can name a lot of things that taste better than skinny feels. Potatoes, bread…Philly cheese steaks and fries."

One year later, Lawrence premiered the hugely successful first film in the Hunger Games franchise, hardly able to comprehend her star status.

"I thought Oprah was behind me," Lawrence joked of the many photographers vying for her attention.

As her prominence rose, so did her paychecks. For Winter's Bone, the actress took home a reported $3,000 a week. The Hunger Games earned about half a million for the Oscar winner, and it's follow-up Catching Fire will rumoredly rake in at least $10,000,000.

Despite the significant rise in income, Lawrence told ET that until a month ago, she was still living with her parents. It's no wonder then that after sweeping awards season this year, Lawrence's folks were never far from her side.
