Britney Spears shaved her hair to avoid drug testing
Britney Spears allegedly shaved her head because Kevin Federline was threatening to test her hair for drugs. K-Fed was at Britney's Malibu mansion last Friday when she got back from rehab and the two got into a huge fight. A source says:

"They had a huge 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."

And after shaving her hair Friday she went to the Mondrian Hotel in an electric blue wig where sources say they saw her shaving her legs at the pool and crying after she was refused a room.

"She didn't have any credit cards, she didn't have any cash... I don't even believe she had any I.D.," dished US Weekly's Katrina Szish. "She was depressed and confused. The general consensus is we're seeing Britney have a breakdown before our very eyes."

Jesus, it's a good thing K-Fed didn't threaten to test Britney's urine. Otherwise instead of checking into rehab we'd be reading about how she died in a mysterious bladder accident after deciding "she didn't need to pee anymore. Ever."
