(MSNBC.COM) 21 January 2007:

Before Britney Spears was cutting her hair off, she was pulling it out.

The troubled pop star was behaving erratically the week before she checked herself into rehab for the second time.

“She would get into bed with [her sons] and talk about moving away and living in a world that’s all their own,” a “pal” told Life & Style Weekly. “It’s so sad. She’s been crying all the time and had been pulling out small sections of her hair.”

Spears was distraught and humiliated by her exes, according to the mag, including Justin Timberlake and Kevin Federline bonding at the Grammys and former boyfriend Isaac Cohen allegedly selling tidbits about their romance to a tab.
