Two of the photos are from a striptease contest held in 2007 and show Rima Fakih performing on a stripper pole for an audience of women dressed in underwear.
It has emerged that Miss USA 2010 Rima Fakih had taken part in a stripping contest sponsored by a Detroit radio station.
According to MyFOXDC.com, Fakih, 23, appeared in several photos on Mojointhemorning.com, a morning show on Detroit's Channel 955.
Two of the photos are from a striptease contest held in 2007 and show Fakih performing on a stripper pole for an audience of women dressed in underwear.
"Congratulations to Miss Michigan Rima Fakih, who was crowned Miss USA on Sunday night! Rima is a Dearborn resident and the first Arab American to wear the crown," Fox News quoted the site as stating.
"Rima is a Mojo In The Morning listener who has joined us in studio and at events. Check out Miss USA Rima Fakih when she won Mojo In The Morning's Stripper 101 contest in 2007," it stated.
According to the website, the judges were strippers and awarded Fakih first prize. The prizes included jewellery, gift cards, adult toys, and a stripper pole for use at home.
Only women attended the event, and Fakih never removed her clothing at the event, the radio station said in a statement.
Miss Universe representatives have contacted the producers of Mojo In The Morning and requested more photographs and information regarding Fakih's involvement in the Stripper 101 contest.
Asked if Fakih's status as Miss USA was in danger, pageant representatives would not answer.
Morning show host Mojo said the controversial photographs were taken from their website where they have been posted for three years.
He said Mojo In The Morning will not release any further photographs and hopes that billionaire Donald Trump, who runs the Miss USA contest, does not ask Fakih to relinquish her crown.
"It would be foolish to consider anyone other than Rima to represent the USA. The photos taken from our website are no more provocative than those on the Miss USA website," he said.
