Diana Ross was ordered to return to Tucson, Ariz., to serve a two-day jail sentence in her drunken-driving case.

The singer, who pleaded no contest to DUI last month, had arranged to serve her sentence in Greenwich, Conn., where she lives. But during her stay, she left and returned multiple times, said City Court Magistrate T. Jay Cranshaw.

Greenwich Police Chief James Walters originally wrote Cranshaw to say that Ross, 59, had completed her sentence, spending 48 hours in custody over three days, including two overnight stays.

Cranshaw asked for a full accounting of the time spent there, and it turns out Ross spent only 47 hours in police custody.
