Pop star Britney Spears did not change her conditions in child-custody case after a hearing held yesterday, according to media reports.

The pop star did not show up in the courthouse though she arrived at the court building. After the security screening, she suddenly said she wanted to leave and was driven away, Superior Court spokesman Allan Parachini said.

Though Spears was not ordered to appear in court yesterday, the hearing had been held at her request, which made it "an unusual situation" that she didn't show, Parachini said.

As a result, LA Superior Court Commissioner Scott Gordon did not make any changes to the current visitation and custody rules.

It was the second time this month that Spears pulled a disappearing act at the courthouse in her custody battle with her ex-husband.

On Jan. 3, Spears refused to return the boys to her ex-husband Kevin Federline at her home. Later there was a standoff, and Spears was sent to hospital in an ambulance.

On Jan. 4, Federline was awarded sole legal and physical custody of their two boys and Spears' visitation rights were suspended.

The next hearing is set for Feb. 4, at which time Spears' attorneys will ask permission to withdraw from the case. A hearing on custody is set for Feb. 19.

A custody trial is set for April. Federline's attorney, Mark Vincent Kaplan, noted outside court that the commissioner has ordered a custody evaluator to report back to him before the trial.
