Britney Spears loses visitation rights to her kids

Britney Spears has lost visitation rights to her two sons, after a row over the boys ended her in hospital.

A Los Angeles judge awarded "sole legal custody and sole physical custody" of Sean Preston, 2, and Jayden James, 1, to Spears' ex-husband, Kevin Federline, until another hearing on January 14.

The ruling comes after comes Federline's attorney Mark Vincent Kaplan called for an emergency session on Jan 4, following Spears' meltdown.

"I'm not happy about any of these events. There are no winners here," E! Online quoted Kaplan, as saying.

Spears is currently being held for mental evaluation at Cedars-Sinai Medical Center in Los Angeles, following her well-publicised meltdown on Jan 3.

The singer had a face-off with police at her home after refusing to turn over two year-old Jayden James to Federline's bodyguard.

After a police intervention, the frantic singer was strapped to a gurney and taken by ambulance to Cedars-Sinai, where she will be held for 72 hours to for mental evaluation.

The 'Toxic' singer lost custody of her children in October after being ruled a "habitual" user of drugs, and was granted two day visits per week with her children plus one overnight stay. (ANI)
