Did you ever do the Butt Dance in a thong?

April 7, 2005 -- VIDEOTAPE of Jenna Bush in very high spirits at a bachelorette party is being sold and could end up on national TV by the end of the week. Luckily for Jenna, the cameraman missed "the high point . . . Jenna on all fours doing 'the butt dance' — and doing it very well — as guys were ogling her thong," said our source. Club patrons do the suggestive dance when the deejay plays the 1988 hit "Da Butt," by E.U. The president's blond daughter arrived at NerveAna, a '90s-themed lounge on Varick Street, at 10:30 p.m. last Friday with several other pretty young things in a battered old blue minivan. Sources said it was Jenna's third visit to the club, which features replicas of Monica Lewinsky's blue dress and O.J. Simpson's white Bronco. Jenna, who plans to teach school in D.C. next fall, wore jeans, moccasin boots and a midriff-baring, satiny blue top. She lit up a cigarette "and she was very polite when she was told she'd have to go outside to smoke," said our source. Before leaving at 3:30 a.m., Jenna and her pals gamely joined a conga line and danced around the club.
