Diva Ross: I've done my time

Singer Diana Ross, ordered to return to Arizona to serve a drink-driving sentence, claims she has already met a state requirement to spend 24 consecutive hours in jail.

"I think we actually have proof from her," said Jim Nesci, a lawyer for Ross. "She documented it in her diary."

Ross pleaded no contest last month to a drunken driving charge in Tucson in December. She arranged to serve her 48-hour sentence in Greenwich, Connecticut, where she lives.

But Tucson City Court magistrate Jay Cranshaw found that Ross failed to serve 24 consecutive hours as required by Arizona law.

Ross served 47 hours in the custody of Greenwich police over a three-day span, Cranshaw found.

On her last stay at the jail, police logs show Ross arrived on February 11 at 8am and stayed for 22 hours until 6am the next day.

Cranshaw has ordered Ross to return to Tucson "to serve 48 consecutive hours in the Pima County Jail" and has scheduled an April 1 court hearing on her sentence.
