LATEST: Pop star Britney Spears has been given one more chance to testify in her child custody case - her deposition has been rescheduled for Thursday (03Jan08), according to reports. The singer skipped yet another a court-ordered deposition on Wednesday (02Jan08) - which resulted in her lawyer Sorrel Trope, of family law firm Trope and Trope, filing a motion with a Los Angeles judge requesting permission to quit the case due to a "communication breakdown" between the attorneys and client Spears. But sources tell celebrity blogger PerezHilton.com Spears has been told to turn up for the rearranged deposition on Thursday at the Los Angeles offices of her ex-husband Kevin Federline's attorney, Mark Vincent Kaplan - or risk a jail sentence. Spears' failure to comply with a string of court orders is likely to have serious repercussions in her fight to regain custody of her two sons, Sean Preston, two, and Jayden James, one. Last month (Dec07), the singer claimed she was too ill to sit for her deposition. That same night she was reportedly spotted out partying.
