Singer and actress Whitney Houston died in Los Angeles on Saturday at the age of 48.

Houston's sudden death has shocked her fans around the world. Waves of mourners gathered in front of the Beverly Hilton Hotel where Houston had been staying as a guest and was found dead.

Police said there are no signs of foul play, and the possibility of the diva drowning in a bath tub has been raised. The exact cause of Houston’s death will be released after an autopsy is completed.

Houston was one of the most celebrated female singers with hits including "I Will Always Love You" and "Saving All My Love For You." She starred in the movie “Bodyguard” alongside actor Kevin Costner.

The singer fell into alcohol and drug addiction after her marriage with American R&B singer Bobby Brown ended.

Houston held a world tour concert three years ago in an effort to make a comeback. Her death on Saturday came on the eve of the 54th annual Grammy Awards.
