Britney Spears' child-visitation rights have been suspended soon following her hospitalization for mental evaluation after the so-called "family custody dispute" on Thursday night, January 3.

A Los Angeles Superior Court judge, who's involved in Brit and Kevin Federline's custody dispute, held an emergency hearing and issued a written order which ruled Spears' children Sean Preston and Jayden James to be placed in the sole care of the singer's ex-husband K-Fed, suspending the pop star's visitation rights until "further order of the court."

The order is in effect until January 14 when another hearing has been scheduled to take place to determine how the bitter custody battle is to proceed.

The court ruling came less than a day after Spears refused to hand over Sean Preston and Jayden James to K-Fed's representatives after having had the children with her for 24 hours. She reportedly barricaded herself inside a room.

Police were called to her Beverly Hills home on Thursday night for what was cited as "family custody dispute." There were six police cars, a police helicopter, an ambulance and a fire engine spotted outside the gates at Britney's home around 10:30 P.M. with the showdown lasted for almost four hours. After hours of intense negotiations, Spears finally turned over her children to K-Fed just before 11:00 P.M.

Was said to be "under the influence of an unknown substance", Spears then being taken to Cedars-Sinai Medical Center for mental evaluation. Her younger son, Jayden James, according to several reports was taken to the hospital at the same time in a separate ambulance.

No words on Spears and Jayden's latest condition. Meanwhile, it has been confirmed that Spears will, by now, not face any criminal charges. "The LAPD is not planning to file any charges against Ms. Spears at this time," Officer April Harding told People. "The investigation is ongoing."
