LATEST: Troubled Britney Spears finally arrived for her deposition in her child custody case on Thursday (03Jan08) - and testified for 14 minutes. The Toxic singer skipped a second court-ordered deposition in her fight over her two sons with ex-husband Kevin Federline on Wednesday (02Jan08), causing her lawyer Sorrel Trope to file a motion requesting permission to quit the case because of a "communication breakdown" with Spears. Last month (Dec07), the star claimed she was too ill to attend court - that same night she was reportedly spotted out partying. But on Thursday morning, Spears presented herself at the office of Federline's attorney Mark Vincent Kaplan in Los Angeles for questioning. She arrived 90 minutes late, and then stayed for less than a quarter of an hour. When asked if Spears had provided Kaplan with all the information he needed, the lawyer replied, "In 14 minutes?!" Spears is expected to be quizzed on subjects including her past drug and alcohol use and her failure to comply with a string of court orders. Spears and Federline's divorce was finalised last summer (07). Both are fighting for the custody of Sean Preston, two, and Jayden James, one.
