Jessica Simpson is talking about about a shocking new diet.

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

Cupping is a Chinese practice where a cup is applied to the skin and the pressure in the cup is determined by a change in heat or by suctioning out the air. The practice is said to help with headaches, acne and acute diseases.

Simpson tweeted about cupping, writing: "Has anyone ever tried cupping? When [you] know you are doing something good for [your] body the meditation creates intense visions. Love it!"
