Britney Spears has reportedly become worried that a sex tape stored at her LA home has been stolen.

The popstar, who is currently residing in the UCLA Medical Center psychiatric ward, had police called to her house on Friday following a break-in, say US reports.

Spears is apparently worried that a sex tape, which also features her taking drugs, was taken during the burglary.

A source is quoted as saying: “This is the last thing Britney needs. She’s on the edge. All her secrets could be revealed.

“Some of the things that may have been taken are dynamite. It doesn’t bear thinking about. They could have anything – all her secrets could be out.”

The singer was rumored last year to have starred in a X-rated video with ex-husband Kevin Federline, but the reports were later quashed.

Earlier this year, another sex tape, allegedly featuring a bald-headed Spears performing sex acts, was reported to have leaked online.
