Britney Spears hospitalized

LOS ANGELES, California (CNN) -- Pop star Britney Spears remained hospitalized Friday, hours after police were called to her home Thursday night to mediate a custody dispute.

Police initially said Spears was taken to a hospital for tests to see if she was under the influence of alcohol or drugs and for a psychological evaluation after the situation at her home, but Officer April Harding said Friday she could not confirm that or other reports that Spears was hospitalized for mental evaluation.

"For her own welfare, she was transferred to a local hospital for medical treatment," Harding said, according to The Associated Press.

On Friday morning, lawyers representing Spears and her ex-husband, Kevin Federline, spent about 30 minutes in chambers Friday with Los Angeles County Superior Court Commissioner Scott Gordon, who has been handling the couple's custody dispute, the AP reported. The attorneys did not comment to reporters. Watch what's going on with Spears' behavior »
