Whitney Houston receiving rehab treatment

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.

The representative told People.com: "Whitney Houston is currently in an out-patient rehab program for drug and alcohol treatment.

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

A source told website TMZ: "She's cleansing herself to get ready for a new movie."

According to the website, 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 ex-husband Bobby Brown's drug use spiralled out of control after she starred in hit movie The Bodyguard in 1992.

She said: "Me and Bobby were lacing our marijuana with base. We would buy a kilo. We were not pipe smoking.

"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, were accused of being a cocaine addict by a former boyfriend but denied his claims.

MOVIE COMEBACK. Whitney is also set to return to the big screen for the first time in 15 years.

The 47-year-old singer-and-actress will be reuniting with her former Waiting To Exhale castmates to create a sequel to the 1995 hit movie, in which she played unlucky-in-love television producer Savannah Jackson.

Angela Bassett—who portrayed Bernadine Harris in the film—explained director Forest Whitaker is in the process of altering author-and-screenwriter Terry McMillan's follow-up to the movie.

Speaking on TV show The Talk, she said: "It's preliminary, but it's going to happen,Waiting to Exhale 2. McMillan wrote Getting to Happy and she's written the screenplay... Loretta Devine, Lela Rochon, Whitney, Forest. Forest is working on the script now."

Meanwhile, it was recently revealed 1992 hit movie The Bodyguard—which starred Whitney and Kevin Costner and took $411 million at the worldwide box office—is to be remade by Warner Bros.

While Whitney—who hasn't appeared in a film since The Preacher's Wife in 1996—won't be appearing in the remake, producers are keen to get a young female singer with global appeal and give her the platform that The Bodyguard provided Whitney.

Beyonce Knowles and Rihanna are two names which have been linked to the project.
