SHEEN IN COURT: Charlie Sheen had a busy day in court Tuesday as he tried to wrest custody of his twin sons from his estranged wife, Brooke Mueller, and his lawyers struggled to quash legal moves by his former studio bosses. Sheen failed in his bid to alter the child custody agreement, with a judge ordering continuation of the current joint arrangement with Mueller. In another Los Angeles area court, Sheen's lawyers met with lawyers for Warner Bros., which Sheen has sued for $100 million, accusing the studio of wrongly firing him this year from the hit series "Two and a Half Men." There will be no immediate decision on whether that case should be heard in public court rather than in private arbitration.

Bullock oversees nonprofit corporations operating in the state. His spokesman said the inquiry has not reached the level of a full-scale investigation.
