With her incredible vocal range and purity, runway good looks and girl-next-door charm, Whitney Houston was an out-of-the-box superstar when she arrived on the music scene in 1985. Her meteoric rise included record-setting hits, groundbreaking videos and a promising film career.

But by the mid-1990s, rumors of marital woes and drug abuse began to tarnish her image and she took a downward spiral that saw her name emblazoned in sordid tabloid headlines rather than glowing reports of musical success.

Word of the 48-year-old singer's death broke early Saturday evening as the industry gathered in Los Angeles for the official Pre-Grammy Gala hosted by her mentor Clive Davis, chief creative officer of Sony Music Worldwide.

Beverly Hills police Lt. Mark Rosen told KABC-TV that Houston was pronounced dead at 3:55 p.m. (local time) in her room on the fourth floor of the Beverly Hilton. Her body remained in the hotel and Beverly Hills detectives were investigating.
