Marketing executive Rima Fakih, 24, beat 50 other contestants to win the beauty pageant in Las Vegas.
But her victory was already becoming tarnished last night by revelations that she won a pole dancing contest at a strip club in Detroit in 2007.
She was photographed sliding up and down a stripper’s pole in a blue tank top, hot pants and high heels.
Other photographs from the competition showed her wearing a bra stuffed with dollar bills.
The photos were posted on the website of a Detroit-based radio show following her triumph at the Miss U.S.A. contest on Sunday night.
The radio show's producers claim they have been contacted by the organisers of the Miss Universe competition requesting additional information regarding Miss Fakih's involvement.
As the winner of Miss U.S.A., the 24-year-old marketing executive from Michigan will represent the U.S. in the beauty contest later this year.
It is not known if organisers of Miss U.S.A. were aware of Miss Fakih winning the 'Stripper 101' contest at the Coliseum Gentleman's Club.
She is believed to have won a variety of prizes, including adult toys and a stripper's pole.
