Britney in new sex tape allegation

A 28-year-old man has claimed to own a sex tape of a one-night-stand with Britney Spears.

The anonymous male told In Touch Weekly that he secretly filmed his night of passion with the 'Gimme More' singer in June, but is afraid to release it because of his poor performance in the bedroom.

He told the magazine: "It was just normal sex, we didn't do anything crazy. It was a little disappointing. It lasted for about 25 minutes and then we passed out."

Spears, who was on holiday in Hawaii, allegedly met the mystery man at a bar before taking him back to her Four Seasons hotel on the Kona Kohala Coast.
