Now that the Oscars are over, we can get back to more important things, like Britney Spears's crazy antics.But she may be crazy like a fox.  According to my sources, the real reason the Popped Princess shaved her head was to outsmart Fed-Ex. "Kevin threatened to have Britney's hair drug-tested," sez my reliable source. "He was going to get a strand of her hair and have it analyzed for traces of drugs. It if tested positive, he could get full custody of the kids. Right after she found out, she rushed to the hair salon and buzzed off the evidence."

Way to go, Brit.  Unfortunately, she forgot one thing. Hair grows back. And if there are drugs in the body, they will continue to show up in the hair for quite some time. So we may be seeing her big old bald noggin for quite a while. Wonder if Kevin realized that as soon as the bald Britney news broke, he could have hit that Tarzana salon and bought a hunk of the hair she left on their floor.
