One of Kirstie's biggest regrets when it comes to her weight gain is letting down the people she motivated to lose weight, she says. "I really want to inspire again," she says.

Kirstie found her own inspiration in Valerie Bertinelli, the current Jenny Craig spokeswoman. In about a year, Valerie lost almost 50 pounds and recently revealed her bikini body in a national commercial!

Kirstie says she was the person who originally encouraged Valerie to join Jenny Craig. "I wanted to take someone else on the journey," she says. "And now the pupil's like A-plus. ... She's surpassed me, but now she's inspired me."
