Britney Spears filmed in 'secret sex video'

Britney Spears is allegedly the star of a new sex tape with a man she met in Hawaii in June.

The 28-year-old has said the only thing stopping him from releasing the video - made without Britney's knowledge - is that he was disappointed by his performance.

He says: "It was just normal sex, we didn't do anything crazy. It was a little disappointing. It lasted for about 25 minutes."

Britney reportedly made a four-hour sex tape with her then husband Kevin Federline in 2004 - a claim she denied.

Britney's personal has continued it's downward spiral in recent days - earlier this week she was forced to hand over custody of her infant sons to Federline.

According to Britney's lawyer, a lack of a valid LA licence was a factor in the decision to award temporary custody of her sons Sean Preston, 2, and Jayden James, 1, to their father.

Britney was issued an interim licence from the California Department of Motor Vehicles yesterday, an agency spokesman said.
