Pop star Britney Spears was taken to hospital for tests to see if she was under the influence of alcohol or drugs and for a psychological evaluation after police were called to her home Thursday night to mediate a custody dispute, a police spokesman said.

Spears appeared to be conscious as she was rolled out of her Studio City home on a gurney about three hours after police and ambulances arrived there.

The children were returned to their father, Kevin Federline, who has primary legal custody of the two sons, a police spokesman said.

Doctors at Cedars Sinai Medical Center in Los Angeles will decide whether to invoke a California law that allows a patient to be held for psychological evaluation for 72 hours, the police spokesman said.

Aerial video provided by local television station helicopters showed Spears on a stretcher and surrounded by police and paramedics as it was rolled to an ambulance near her home.

Spears has been in a heated battle with ex-husband Kevin Federline over custody of their two sons, Sean Preston, 2, and Jayden James, 1.

Federline, Spears' former backup dancer, holds primary custody of the children. Spears has been in trouble with the court earlier concerning her compliance with court orders in the custody case.
