Sean “Diddy” Combs has returned to court a week before the Grammy-winning hip-hop producer faces sentencing for his July conviction on two prostitution-related charges.

Judge Arun Subramanian listened to arguments from lawyers on points of law that might help him decide how long the Bad Boy Records founder must spend behind bars. The 55-year-old Combs will have been jailed for nearly 13 months when he is sentenced on Oct. 3.

His lawyers, noting that he was acquitted of the most series charges he faced, say he should go free now. Prosecutors say he should spend years more locked up.
