A surveillance tape reportedly showing troubled pop star Britney Spears getting intimate with two female dancers at a New York club has become the latest hot property for internet porn companies.

Spears changed into fishnet stockings and a bikini while partying with dancers at nightclub One on February 12 - and things allegedly got steamy with the threesome.

When a manager at the club discovered damaging video footage of the incident, the dancers were subsequently sacked.

A source tells the New York Daily News, "The manager said there was a tape of them. Both girls cried about it when they got fired, but they didn't deny it."

Adds another source, "If that thing gets on the internet, there's going to be big trouble."

According to the newspaper, there are also pictures of Spears' bare bottom, which were taken while she was trying on clothes with the dancers.
