Ooh...

More Britney action.

Apparently on Friday (the day she shaved her head) she and The Fed had a big argument:

"Kevin threatened Britney that he was going to have people test her hair to find out exactly what she's been up to. She was so scared. That was what made her have her head shaved."

This is according to a source talking to OK magazine. This is interesting, although I don't know that I've ever heard of a mandatory hair test. Can you test someones hair for drugs and stuff? And surely it would be the hair at the root that would be most telling of recent behaviour, so all the hair that sprouts from her now-bare scalp is going to have reams and reams of stories to tell...hmm. Someone get me that hair!

According to Splash News Online, her family staged an intervention last week...

Sources close to the singer told Access Spears checked into rehab yesterday, the same day a tearful Lynne Spears, Britney's mother, told Access "we love our daughter." This is not Britney's first time in rehab. Access Hollywood has learned that on Valentine's Day, the Spears family staged an intervention with the pop star and shortly thereafter helped the pop singer check into a facility. "She hasn't been reasonable in a good while," the source said. Britney has been drinking and partying and she has suffered from years of "instabilities," the source added ... The source close to Spears however said "it's not just stardom" at fault for the singer's recent actions. Spears' needs "deep healing with [her] family." Britney's recent moves are of little concern to the pop princess' parents. They just want her well, the source said and "will not give up, ever." They have also asked those who know and love Spears, to "pray for help."

P.S. Remember when Britney used to look like this picture above? Those were the days.
