Celebrity Gossip's

Britney Spears, who has been living recklessly since the breakup of her marriage with Kevin Federline in November checked herself into rehab earlier in the week, but checked herself out again after just 24 hours, according to People Magazine Friday.

But that's not the oddest Britney Spears news. Also, a bystander interviewed by L.A.'s KABC-TV, which filmed Spears heading into Body & Soul Tattoo on Ventura Boulevard, said that the pop star had shaved her head because "she didn't want people touching her anymore."

Celebrity photo Website X17 also captured before and after pics of Britney doing the job herself with an electric razor, because apparently she wouldn't let anybody touch her hair either.

Spears, 25, arrived at Eric Clapton's Crossroads Centre in Antigua "two or three days ago" but left after just one day and headed to Florida, an unnamed source told the magazine.

Her former personal assistant, Felicia Culotta, recently revealed that the former pop star and now wannabe mother of two was going off the tracks.

"There's just so much you can do to help a person," Culotta wrote in a letter to Hollywood.com. "I cannot save her from herself, nor can I commit her to any type of treatment programme against her wishes and will."

"By the time I met Britney she was burnt out. She knew she had been drinking and partying as a way to try to banish the bad stuff from her life. Far from the trashy drunk, I saw a very shy, sweet girl who was just desperately sad about what had happened with her marriage," the former pop singer’s ex-boyfriend, model Isaac Cohen, shared his impression on Britney in a tell-all interview with British newspaper, News of the World.

"It was far too soon for her to get involved in a relationship with anyone. It was clear she was not over her marriage. The first time she invited me to her home I saw her wedding dress hung on the wall in a glass box. As we made love that night it was like Kevin was in bed beside us. She had not even begun to move on with her life," he added.

"Other times, she got so low she didn't care what she looked like. She could not care less some days if she went out of the house without brushing her hair or checking to see if her outfit matched."
