LOS ANGELES - Charlie Sheen and Denise Richards, who seemed to have reconciled, have filed legal papers asking a private arbitrator to handle their divorce.

Lawyers for the couple filed the papers Wednesday in Los Angeles, said Sheen's publicist, Stan Rosenfield. "They asked the court to go to a private arbitrator. They want to keep it private," he said.

Richards' publicist, Cheryl Maisel, also confirmed the filing but refused to elaborate.

Richards filed for divorce in March after three years of marriage. The relationship appeared to dissolve in the public eye just months before the 34-year-old actress gave birth to the couple's second child, Lola, in June. They also have an older daughter, Sam.
