Ally McBeal creator David E. Kelley won't be giving

Robert Downey Jr. a third chance. In the wake of Downey's latest arrest, Kelley has fired the troubled actor from the Fox dramedy and will rewrite the show's two-part season finale to exclude his character. "Robert is a unique talent and a very special person, and we wish him the best and hope for a full recovery," read a statement from David E. Kelley Productions. "We are wrapping up the stories on the final few episodes of Ally McBeal for the season without him." Downey was arrested early Tuesday morning in the Los Angeles suburb of Culver City for allegedly taking an unknown "stimulant." The Oscar-nominated Chaplin star — who was on foot at the time — was given a urine test and released to his parole officer. "Robert Downey Jr. has voluntarily checked himself into an undisclosed rehabilitation facility," says his spokesperson, Alan Nierob. In November, Downey was arrested in Palm Springs for drug possession. He's due back in court on Monday in Indio, Calif. for a hearing in that case.
