Jessica Simpson Vegan: Celeb Tweets Her Diet Secrets

(CBS) Jessica Simpson has gone vegan and the "Price of Beauty" star wants everyone to know it.

"Shocked my system with a vegan diet," Simpson tweeted on Sunday. "Special Pu-erh tea from China, and cupping since friday! Who am I right now? This might be too clean!"

Typically, vegans forgo all meat, poultry, fish and animal products like milk, eggs, and cheese.

Simpson has been on a long process of re-invention and introspection.

Earlier this year, she told Oprah she was happy with a new heavier body size.

"I'm comfortable with me. I love my curves. I'm not ever going to be a size 0 and weigh 90 pounds," she said. 

Simpson's cable series "Price of Beauty" follows the 29-year-old and two friends as they explore the sometimes extreme lengths women around the world must undergo for beauty.
