Whitney Houston is headed back to rehab. The singer has signed into an outpatient program for drugs and alcohol, Houston’s spokeswoman confirms. The rep says Houston voluntarily entered the program in order to keep up her “long-standing” recovery process.
In 2002, Houston spilled details of her drug use to Diane Sawyer admitting that she’s experimented with cocaine, marijuana, alcohol and pills, but swore that the “party’s over.” She first entered rehab herself in March 2004 to deal with a substance abuse problem, but left after just five days. She returned a year later.
