Whitney Houston is set to return to the big screen for the first time in 15 years, reports CTV.

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.

Actress 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.

“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.”

In others news, a representative for the superstar singer confirmed today that Houston is undergoing treatment. Kristen Foster says Houston is in an out-patient program for drug and alcohol treatment. She says it is a voluntary measure and part of Houston’s “long-standing” recovery process.

Houston has battled problems with drug addiction for years. But in 2009, as she released a comeback album, she declared herself healthy and clean.

However, her 2010 tour overseas was trouble. Houston cancelled some dates due to illness and received negative reviews from fans who were disappointed in the quality of her voice and performance.

It’s unclear how long Houston will be in rehab or where she’s being treated. But before she takes on the stress of doing huge films, it’s good she clears her mind and focuses on herself first.
