Why Britney Spears Shaved

Britney's decision to shave her head was reportedly the masterwork of Kevin Federline. After the estranged couple had a "screaming match" last week, Britney's very public meltdown began. New York Daily News reports:
"They had a huge argument," a source told the magazine. "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." Testing her hair could determine whether she had been abusing illegal drugs, which could be used against her in the battle for custody of their two young children."
