Paris Hilton's bikini waxer has spoken out about the hotel heiress's trend for flashing her bare private parts in public.The 25-year-old socialite has made a habit of being photographed getting out of cars wearing short skirts and no underwear since August 2002 and has recently encouraged new friend Britney Spears to do the same. Cindy Barshop, owner of the Completely Bare Salon, in New York, believes Paris is comfortable flashing her privates because she is always so well groomed down below. Cindy told Us Weekly magazine: "Paris is a customer of ours. I haven't done Britney, but we do see Paris for bikini waxes. I feel that if you do a completely bare wax, you feel cleaner, more comfortable and more groomed -it seems a little sexier."I think that with the completely bare waxing, they just feel comfortable enough with their bodies that they can skip the underwear. And, oops, if they do happen to flash someone, it's not as embarrassing because the area is groomed."Since mother-of-two Britney filed for divorce from Kevin Federline she has befriended Paris and has been pictured flashing her vagina on four separate occasions. It is rumored that the lewd behaviour is part of an initiation process into Paris' friendship group as her sometime pals Lindsay Lohan and Nicole Richie have been pictured doing the same.
