Britney Spears‘ pal Sam Lutfi tells PageSix.com that the pop singer is being taken to a Los Angeles hospital to be put on psychiatric hold for the second time this month.

LAPD confirmed to us that they responded to a call at Brit’s Beverly Hills home this evening. Since then, X17 has reported the arrival of an ambulance and numerous police vehicles.

Despite a Friday appointment with a psychiatrist and Tuesday’s reunion with mom Lynne, Britney’s behavior had been increasingly erratic over the past few days.

For the second time in a less than a month, police involuntary committed Britney Spears early Thursday morning, hours after blogs and media outlets began reporting that her psychiatrist determined she was a danger to herself and others.

At approximately 1 a.m., dozens of Los Angeles Police officers along with an ambulance arrived at Spears’ home in the Summit Circle gated community in the hills above Beverly Hills. Less than 20 minutes later, she was transported to UCLA Medical Center.

Citing unidentified authorities, The Los Angeles Times said Spears was placed on a “mental evaluation hold.”

The ambulance was seen pulling out of the side entrance of Spears’ gated Summit community at 1:20 a.m. Her mother, Lynne Spears, was seen riding in an SUV as part of the police escort caravan.

Her father, Jamie, and her brother, Bryan, arrived at the hospital minutes after Britney was brought in. Sam Lutfi and Alli Sims also were seen entering.

Lutfi recently told Barbara Walters that Spears — whose behavior has become increasingly erratic — suffers from “mental issues which are treatable” and “that she has been to a psychiatrist.”

On January 3, Spears was taken to L.A.’s Cedars-Sinai Medical Center after a three-hour stand-off with authorities, which began when she refused to hand over her two sons, Jayden James and Sean Preston, to her ex Kevin Federline as required by their custody decree. Spears was released less than 48 hours later.
