RadarOnline.com has an exclusive clip of Kelly's first show under this new deal. in the extremely candid clip, Kelly reveals "the first time I took a prescription pill that wasn't prescribed to me I was 15."  She had just moved to America and didn't fit in "I was the chubby foreigner," she tells Dr. Phil. When she went to a club and felt uncomfortable, someone gave her a prescription drug.

"Because it came from a doctor's bottle I didn't think it could do anything bad, so I took it," she says. "And within 45 minutes. I was the life of the party. And I had confidence. " She finally fit in. "The thing about pills is you don't have to have the right hair. You don't have to have the right bag. You don't have to be the prettiest girl in the world. You don't have to be the most popular. You take a pill and you fit in."
