Jennifer Aniston joined the cupping club last April. Though it appeared she tried to cover the circular marks with a bit of concealer, there was no mistaking them on her tanned back when she turned up on the red carpet wearing a strapless Dior tuxedo-style bustier at the Los Angeles premiere of "Call me Crazy."
Gwyneth Paltrow may well have started the cupping trend in Hollywood. She first appeared with the red marks back in 2004 at a New York film premiere. The natural health care enthusiast later explained that she turned to the procedure to alleviate back pain.
Jet-setting fashion designer and busy mom of four, Victoria Beckham was seen with a row of the telltale marks down her back when she landed at Heathrow Airport in July 2010.
A couple months after beginning her VH1 series "The Price of Beauty," Simpson went under the cup in June 2010. "Shocked my system with a vegan diet, special Pu-erh tea from China, and cupping since friday!" she told her Twitter followers. An instant fan of the procedure, she tweeted a few minutes later, "Has anyone ever tried cupping? When u know you are doing something good for ur body the meditation creates intense visions. Love it!"
