Hanging out with models while filming her reality show, The Price of Beauty, made Jessica Simpson sick -- literally.
"Going to Paris, I had to walk a runway with all these tall skinny models and I almost puked I was so nervous," she said Friday while promoting The Price of Beauty on a Television Critics Association panel in Pasadena, Calif.
Continued Simpson, 29, "I mean, I can walk a red carpet but walking a runway, I will be the first to fall on my face. And thank god I didn't. But I was so nervous to walk out there and be judged. To just put myself out there like that. Especially next to people that eat just salad."
Filming the show "changed me completely," Simpson claimed. "I haven't always had an inner confidence and I haven't always looked at my reflection and loved it. There's always something I've wanted to fix because there's always somebody that looks better. And that's what we always try to compare ourselves to. I think the journey really was finding what is beautiful inside of me and knowing that I own it and it's unique. Rare. It was a very powerful journey."

Now, Simpson says she feels "carefree" about her looks. "I definitely carry myself different after experiencing this because there is something about myself that is so unique that I found that I'm proud of.
"Any man I find, they're gonna be darn lucky!" added Simpson, who just split from Billy Corgan.
VH1 executives announced Friday that the show will debut on March 15 at 10 p.m.
The singer traveled to Japan, Thailand, France, Brazil, Uganda, Morocco and India to study what "constitutes beauty" around the world for the show, which is produced by the same group behind Wife Swap and Secret Millionaire.
Simpson, who serves as an executive producer alongside her dad, has long faced scrutiny for her fluctuating curves.
On Thursday, bloggers mocked her oversized breasts in an ill-fitting top. Last fall -- after a Fox NFL parody mocked her weight by saying she'd make a good "defensive tackle" -- she Twittered, "I will never understand why people attack for a laugh."
