Jessica Simpson: I Almost Puked Next To Skinny Models

Jessica Simpson's weight is in the news again.

While promoting her new VH1 reality show, 'The Price of Beauty,' Jessica admitted that filming a runway segment alongside skinny models made her sick to her stomach.

"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 at a press conference. "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."

She didn't puke in that particular instance, but, she said, "I throw up in a couple episodes."

In the show Jessica travels the world to try to determine what different cultures consider beautiful. One thing she learned: Brazil is "the largest for butt implants, definitely for plastic surgery."

Jessica and her father Joe executive produced the show, which premieres March 15.
