A gifted R&B-pop-gospel singer possessing the most astonishing vocal range since Barbara Streisand, the model-turned-songstress Whitney Houston hit the scene in a big way in 1985, successfully alternating danceable mainstream pop with plush ballads on her self-titled debut album. Over a short period, she became one of the most successful female solo artists in the history of recorded music. No slouch in the acting department, Houston had the looks and talent for the big screen as well. Without question, she made her biggest onscreen splash as the damsel-in-distress in the iconic romantic-drama, "The Bodyguard" (1992) opposite Kevin Costner. She would later draw favorable reviews for other memorable films, including "Waiting to Exhale" (1995) and the "Preacher's Wife" (1996), but it was impossible to top the success of her freshman film effort and its seemingly omnipresent song, "I Will Always Love You." Unfortunately, a decade later, things began going downhill for Houston, with rumors of drug abuse, cancelled stage appearances and overall chaos reigning between the singer and her husband, R&B singer Bobby Brown. Following her divorce from Brown and a period of seclusion, she attempted a comeback with a new album in 2009 and world tour in 2010. Houston's return to outpatient rehab a year later suggested the struggling diva had more work to do on herself. Despite setbacks, fans remained devoted to Houston and waited for a comeback that never came. On Feb. 11, 2012, the beloved singer passed away at age 48, shocking the public and the music industry who were gathered that weekend to celebrate the Grammy Awards.
