Britney Spears is "on the edge" after discovering sex tapes were stolen from her Beverly Hills home.
The troubled singer - who is currently undergoing psychiatric treatment at Los Angeles' UCLA Medical Center - is said to be terrified that "valuable items" taken from her sprawling mansion on Friday night (01.02.08) included X-rated footage of her taking drugs and having sex.
A source close to the singer said: "This is the last thing Britney needs.
She's on the edge because all her secrets could now be revealed. Some of the things that may have been taken are dynamite."
This would not be the first time Britney has been involved in a sex tape scandal. Footage apparently showing the singer performing oral sex on ex-husband Kevin Federline was leaked on the Internet last year, but was eventually classed as fake.
More recently, there were reports of Britney, 26, starring in another sex tape where she sported a shaven head and performed a sex act on two women and a man while consuming cocaine and marijuana. However, the footage was never made public.
Los Angeles Police Department officer Alex Martinez confirmed police had responded to a call originating from Britney's house, but said he had no idea what had happened, adding: "The report is being processed through our system. We do not have access to it."
Meanwhile, Britney - who was involuntarily committed to the Stewart and Lynda Resnick Neuropsychiatric Hospital at UCLA last week after being classed as G.D. (gravely disabled) - will now spend an additional 14 days in the ward, after her psychiatrist deemed she wasn't well enough to leave.
Britney - who is now legally under the care of her father Jamie Spears following a court hearing on Friday - has already been transferred to a 'quiet room' after arguing with doctors following her committal.
A hospital insider told People magazine: "It is a terrible situation.
Britney is in a padded room. Her family is so worried about her." |
