According to her official website, Houston has sold more than 170 million albums, singles and videos over her career.

That includes seven straight Billboard No. 1 hits in the 1980s, including “Saving All My Love for You,” “Greatest Love of All” and “Where Do Broken Hearts Go.” Billboard claimed that her soundtrack to the movie “The Bodyguard” is one of the top 10 biggest-selling albums of all time.

The daughter of singer Cissy Houston, Whitney was born on August 9, 1963, in Newark, New Jersey. Famed music producer Clive Davis reportedly spotted Houston 20 years later in a New York nightclub, signing her on the spot, according to her website.

In May 2011, Houston got help for her much-publicized struggle with drugs and alcohol, her representative said at the time.
