Is Brit Headed for a Breakdown?

After checking herself out of rehab and slumming it in coach on an American Airlines flight back to L.A., Britney Spears had something to prove. As soon as she landed, Brit stopped at a Tarzana salon and asked them to shave her head. When the hairdresser refused, a source says Spears "grabbed the hair clipper and started doing it herself," reports Us Weekly. Then she jetted over to Body & Soul Tattoo in Sherman Oaks, where employee Emily Wynne-Hughes says the singer was agitated and a "nightmare" to deal with. When asked about her new 'do, an exasperated Britney told Hughes, "I don't want anyone touching me. I'm tired of everyone touching me." Her two new tattoos -- a black, white and pink cross on her hip and red and pink lips on her wrist -- cost $80. During the one-hour visit, the employee noticed a stain on the singer's white handbag, and Brit explained she had "spilled Nyquil all over it." The employee says it was clear that the fallen pop princess was "on the verge of a nervous breakdown."
