From the NY Post:
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.
If there is a tape, it’ll be on the web by the end of today. Mark my words.
