Kylie Bisutti hit the big time at the tender age of 19 when she beat out 10,000 bikini beauties to win the 2009 Victoria’s Secret Model Search. So why was Bisutti nowhere to be seen during last year’s Victoria’s Secret runway extravaganza?

“Victoria's Secret was my absolutely biggest goal in life, and it was all I ever wanted career-wise. I actually loved it while I was there, it was so much fun and I had a blast. But the more I was modeling lingerie, and lingerie isn't clothing, I just started becoming more uncomfortable with it because of my faith,” Bisutti told FOX411’s Pop Tarts column. “I'm Christian, and reading the Bible more, I was becoming more convicted about it.”

The California native, now 21, said that in the wake of baring her body as an Angel, she was also hosting parties, posing for men’s magazines, and craving more and more attention.

But she was not feeling good about herself.

“My body should only be for my husband and it's just a sacred thing," said Bisutti, who had gotten married just before winning the 2009 modeling competition. "I didn't really want to be that kind of role model for younger girls because I had a lot of younger Christian girls that were looking up to me and then thinking that it was okay for them to walk around and show their bodies in lingerie to guys.

“It was pretty crazy because I finally achieved my biggest dream, the dream that I always wanted, but when I finally got it, it wasn't all that I thought it would be. Especially being married I just wanted to keep my marriage sacred because divorce rates now in America are pretty high, and I just want to do everything I can to keep my marriage special.”

However, Bisutti hasn't left the entertainment industry entirely, just the posing in underwear part. She appears with Jennifer Lopez in a new Kohl’s commercial, and she'll be working on a new show set to air on the CW channel in September. Bisutti says she's glad she made her career shift, before it was too late.

“It is a very hard industry to be in without falling into things you don't want to do," she said. "I've fallen into many things that I wouldn't have wanted to do, it's a very tempting industry.”

“My goal is just to be a better role model for the youth, I just want them to see me as somebody that they can look up to and somebody that's going to be dressing appropriately and I'm not going to get into things that I wouldn't want them to be getting into,” she added. “I want to go over the top because I don't think enough people go over the top about how serious all this is.  I just want people to see something different about me because I have that faith and I think it's so important for everyone to have.”
