Britney Spears suffers from multiple personality disorder, it has been claimed. The 'Piece of Me' singer has been overheard speaking in a British accent recently and it is claimed 'the British girl' is an identity the mother-of-two cannot control.

A source told gossip website TMZ.com: "Britney has multiple personalities, including 'the British girl', as we call her. She goes into this identity and gets a British accent, but when she comes out of it she has absolutely no idea what she did during that time."

"She has other identities and we have given a lot of them names. There is the weepy girl, the diva, the incoherent girl and many more."

Britney, 26, was hospitalized for a psychiatric evaluation on January 3 following a three-hour stand-off with police at her Beverly Hills home, when she refused to return sons Sean Preston, two and 16-month-old Jayden James to ex-husband Kevin Federline.

As she was wheeled out to the ambulance, strapped to a stretcher, she was caught on video speaking in a British accent. The insider also claims she had become 'the British girl' the day she did not attend her court ordered deposition and claims to have no recollection of it.

Meanwhile, Britney's friend Sam Lufti gave a telephone interview to Ryan Seacrest's radio show, denying she is pregnant and insisting she has no plans to marry her new photographer boyfriend Adnan Ghalib.

Britney can be heard on the phone during the interview, talking from the shower. She said: "Get out, I'm naked, get out!"

Asked by Lufti why she's taking a shower, Britney said: "I stink, 'cause I'm a human being. Shut the door, I'm nasty!"
