Following her August 27th arrest for possession of heroin and cocaine, Mackenzie Phillips has entered rehab.

Phillips has been charged with two felonies, for possession of heroin and cocaine, and a misdemeanor, for unauthorized possession of a hypodermic needle or syringe. She faces over four years in prison if convicted. Her arraignment is set for October 3rd.

Bijou Phillips and boyfriend Danny Masterson (in the far back, over Bijou’s left shoulder) leave the Van Nuys police station after visiting Bijou’s half sister Mackenzie Phillips who was arrested on drugs charges Wednesday morning after she was found in possession of what was allegedly cocaine and heroin while passing through security at LAX.

Mackenzie needs help so she really can take it One Day at a Time. What? Too soon?

Former One Day at a Time star Mackenzie Phillips, 48, was arrested at Los Angeles International Airport on Wednesday on suspicion of drug possession.

While being screened by airport security they found baggies and balloons believed to be heroin and cocaine. She was arrested at around 10am, booked at the Van Nuys police station and bail was set at $10,000.

The actress, daughter of legendary Mamas & Papas singer John Phillips, has a long history of drug addiction and failed rehabilitation. We hope she gets the help she needs.
