Redmond O'Neal, the son of Ryan O'Neal and the late Farrah Fawcett, was transferred from county jail to a California drug treatment facility on Thursday, says a new report.

People.com reports that the 24-year-old entered an inpatient drug rehab facility in Pasadena, Calif., where he will be treated for one year.

A Los Angeles Superior Court judge said O'Neal was "doing extremely well," according to the mag.

His attorney tells People: "Redmond has embraced recovery. All of his reports are extremely positive. He has taken huge steps towards his new life. This has been a very challenging time for Redmond. He lost his mother while in recovery. He loved his mother dearly and that was extremely hard on him. It would be challenging for anybody, much less a 24-year-old coming to grips with his addiction and recovery."

Redmond was temporarily released from jail back in June to attend the funeral of his beloved mother, who passed away on June 25 after a battle with cancer.

He is expected back in court on Sept. 30 for a hearing on his DUI arrest and probation violation from earlier this year.
