LASHING OUT

Hot on the heels of her less than 24-hour stay in rehab, the troubled singer stops by a hair salon in Tarzana, Calif., on February 16, 2007, and shaves her hair off. A week later, she attacks a parked car with an umbrella outside of ex Federline's home when he refuses to let her in to see their kids.
