Britney hospitalized again for evaluation

Britney Spears was hospitalized at UCLA Medical Center for a psychiatric hold after being transported by ambulance from her Studio City home.

The singer, 26, was transported to UCLA for treatment and evaluation during a 72-hour emergency hold, known as a 5150.

Spears's mother, Lynne – who's in the midst of a tense reunion with her daughter – friend Alli Sims and Lutfi were all inside the gated mansion when police and the fire department arrived.

What brought on the hospitalization? "She was driving around her neighborhood like a mad-woman," says a Spears family source. "Britney has been prescribed medication which she refuses to take. This is just another sad, sad evening."

Lutfi and Spears's father, Jamie, arrived at the hospital shortly after the singer. Her mother was later spotted leaving the Summit home with Spears's photographer beau, Adnan Ghalib, in the backseat.

Since the January standoff, Spears has been stripped of visitation rights for her two sons Preston, 2, and Jayden, 1. Two sources have said she suffers from a psychological disease, with one source saying, "there is no question she is bipolar ... she's had manic episodes for years."
