The troubled son of late Charlie's Angels actress Farrah Fawcett and Ryan O'Neal is back in prison.
Twenty-four-year-old Redmond was taken into custody on December 29 for an alleged drug-related probation violation, it has been revealed.
He had been undergoing an in-prison rehab programme while waiting for a February progress report in relation to his previous drug charges.
"It seems to me you haven't got a clue as to what recovery means," an LA judge told Redmond.
"It's a lifetime commitment. It's grinding, hard, painful work."
Redmond reportedly tested positive for drugs after admitting to his counsellor that he had been using.
