Los Angeles, Feb. 18 (Reuters): A tearful Britney Spears defiantly shaved her head at a Los Angeles hair salon after the owner refused to take part in the embattled pop star’s latest extreme makeover, news reports said on Saturday.

The Friday evening visit to Esther’s Haircutting Studio in the Tarzana district of Los Angeles was followed by a trip to a tattoo parlour where the 25-year-old mother of two young sons added two designs to her body.

The transformation came on the same day People magazine and other entertainment media reported that Spears recently entered a rehabilitation centre in the Caribbean island of Antigua and checked out a day later. The reports were denied by Spears’s representatives.

Spears’s busy Friday night began in the salon of Esther Tognozzi, who told the syndicated television gossip show Extra that she was afraid to shave Spears’ head in case she was sued for ruining the singer’s image.

After Tognozzi protested that Spears was maybe being “hormonal” and would feel differently the next day, Spears coolly “grabbed the buzzer and started buzzing her own hair off.... I just cleaned it up when she was done with it,” she said.

Tognozzi said Spears seemed to be “just there in body and not really emotionally there”, but did get “a little bit teary-eyed” when she realised her mother might get upset.

The whereabouts of the hair was a mystery, although an enterprising person in Pennsylvania was selling 10 lots of the purported locks on eBay at $50 per lot.

After Spears’s bodyguard paid Tognozzi a tip, the party headed to the Body and Soul parlour in the suburb of Sherman Oaks, where she spent $80 for a black-white-and-pink cross on her lower hip and red-and-pink lips on her wrist.

An artist at the parlour, Emily Wynne Hughes, said Spears appeared “distraught and disturbed”, and was difficult to work with.

“She was screaming and flipping out from the pain and wiggling her body all around,” Hughes told reporters.

Spears’s representatives could not immediately be reached for comment.
