Redmond O’Neal, and his father Ryan O’Neal, were both arrested in September when cops did a routine search of the house, and found crystal methamphetamine in Ryan’s room.

On Wednesday Redmond finally admitted in to a Los Angeles Superior Court Judge that the meth was his, and he had a drug relapse. The judge said:

"You’re a stand-up guy to come here and deal with your problem. I want you to stay clean. … You better stay clean or the hammer is going to fall."

Redmond has to go to rehab for 2 weeks. Wow, that’ll cure him. I can hear the sound of that hammer falling already.

Ryan O’Neal (67) and son Redmond O’Neal (23) were both arrested for Methamphetamine possession at 8:02 am this morning. Sheriff’s deputies say they performed a "routine" probation search of the home, when they found what "appeared to be methamphetamine" in Ryan’s bedroom. The probation was part of Redmond’s sentence after he pleaded guilty in June to two felony counts of possession and one misdemeanor count of driving under the influence.

Redmond’s half-sister Tatum O’Neal (44) was also busted for crack in June.

Both Ryan and Redmond were released on bond this afternoon. Hopefully rehab is on their to-do list.

Redmond O’Neal (23) son of actors Farrah Fawcett and Ryan O’Neal, was arrested on DUI and felony possession of heroin and methamphetamine on January 26, 2008, in Malibu. Today he plead no guilty to those charges. Initially police had pulled Redmond over for speeding on the Pacific Coast Highway, then realized he appeared really high. Look how dialated his pupils are in the mug shot.

In 2005, Redmond pleaded guilty to possession of cocaine and methamphetamine. He is due back in court May 29.

Hopefully he cuts a deal with the prosecutor. Nicole Richie got a second DUI, and she was in and out of jail the same day. Of course, Redmond doesn’t have the luxury of getting pregnant before his court date either.
