Gwyneth Paltrow at the opening of her gym

Gwyneth Paltrow allegedly acts like a diva in her own gyms.

The 'Thanks for Sharing' actress, who exercises for two hours a day, six days a week, owns her own chain of workout studios with her personal trainer and good friend Tracy Anderson but reportedly makes their staff clean everything thoroughly for her before she uses the facilities.

A source told Life & Style magazine: "Before she showers, Gwyneth makes someone go into the stall and wipe the entire shower dry!

"She refuses to touch what she calls 'somebody else's shower water.'"

The 40-year-old star, who co-owns five gyms with Tracy, including two in Los Angeles, as well as studios in The Hamptons, London and New York City, also only likes to quench her thirst with a particular brand of water and staff has to go out and get it especially for her.

The insider said: "When she's there, they have to send someone to the gas station to buy a couple bottles of SmartWater. She made such a fuss about it not being stocked, but she doesn't come in often enough.

"She also refuses to use toilet paper that anyone has touched and demands an unopened package. It's nuts."
