LOS ANGELES — Locked in a bitter custody battle that saw her children temporarily removed from her care this week, pop star Britney Spears has other public image concerns, as well. In Touch Weekly has reported that a new Spears sex tape has surfaced and is being shopped.

A 28-year-old man, Spears’ alleged co-star in the tape, told In Touch that he met Spears in a bar on June 7, while she was on vacation. He allegedly filmed the risqué action in a bungalow at the Four Seasons hotel on Hawaii’s Big Island. The man said that he left the camera rolling without Spears’ knowledge.

“It was just normal sex, we didn’t do anything crazy,” the man told In Touch. “It was a little disappointing. It lasted for about 25 minutes and then we passed out.”

This is not the first time Spears has been embroiled in a sex tape controversy. News of a sex tape between Spears and estranged husband Kevin Federline first surfaced in late 2005 after a member of the couple’s entourage threatened to make it public. Federline’s lawyer publicly denied its existence and the tape was not released.

Celebrity sex tape marketer Kevin Blatt told XBIZ that he is looking into the validity of the sex tape rumors.

“I’m not sure I buy [that a sex tape exists], but I have been contacted about it and I’m personally making calls and looking into it. I have doubts that it will be released, but it could always be leaked on the Internet.”
