has lost visitation rights for now with sons Preston, 2, and Jayden, 1, according to a court document released Thursday.
"[Spears's] visitation with the minor children is suspended pending [her] compliance with court orders," the document reads.
No further explanation was given.
But a source close to Spears says the judge removed visitation rights after the pop star was unreachable by a cell phone designated for court-related scheduling. "She waited by the phone," says the source. "It never rang." It turned out the phone wasn’t getting reception at her house, the source says.
On Sept. 17, Spears was ordered to complete a long list of court requirements, including random drug tests, work with a parenting coach, and counseling.
The ruling, first reported by TMZ.com
, was handed down by L.A. Superior Court Commissioner Scott Gordon after Kevin Federline
's lawyer requested an emergency hearing Wednesday.
A lawyer for Spears declined to comment.
After being temporarily stripped of custody on Oct. 1, Spears had been granted visitation rights with access roughly every other day with her sons. She was allowed an overnight visit
once per week with the children after making a personal appearance in court last week
Both Spears and Federline are required to attend the next scheduled hearing on Oct. 26.
