Whitney Houston back in rehab

Whitney Houston is seeking help for drug and alcohol problems.

The 47-year-old singer who has a history of substance abuse issues voluntarily entered an out-patient rehab program around 10 days ago, her spokesperson has confirmed.

“Whitney Houston is currently in an out-patient rehab program for drug and alcohol treatment,” the rep said.

“Whitney voluntarily entered the program to support her long-standing recovery process.”

Angela Bassett revealed earlier today that she and Whitney who hasn’t appeared in a film since The Preacher’s Wife in 1996 are to work together again on a sequel to 1995 movieWaiting To Exhale and it is believed the singer sought treatment prior to relaunching her big screen career.

“She’s cleansing herself to get ready for a new movie,” a source said.

According to TMZ, the treatment program allows Whitney who was pictured at a Prince concert last weekend to go out in public as long as she has a monitor.

In 2009, Whitney confessed to being a cocaine addict herself in TV interview with Oprah Winfrey and admitted her and her ex-husband Bobby Brown‘s drug use spiraled out of control after she starred in hit movie The Bodyguard in 1992.

“Me and Bobby were lacing our marijuana with base. We would buy a kilo. We were not pipe smoking,” she said.

“You roll it up and you smoke it in your weed. It’s almost like heroin cocaine speedballs but you level it off with marijuana.”

Earlier this year, Whitney and Bobby’s daughter Bobbi Kristina, 18, was accused of being a cocaine addict by a former boyfriend but denied his claims.
