(CNN) -- Legendary pop singer Whitney Houston has died at age 48, representative Kristen Foster said Saturday night.
The cause and location of her death was not immediately known. According to her official website, Houston, who struggled with addiction problems over the years, sold more than 170 million albums, singles and videos over her career.
Houston was set to appear in this year's "Sparkle," a remake of the 1976 hit, which was loosely based on the story of The Supremes. It was her first movie role since 1996's "The Preacher's Wife."
