Beverly Hills police are releasing some of the details surrounding the death of singer Whitney Houston. 

Police say Houston's bodyguard found her unconscious in the bathtub of her room at the Beverly Hills Hotel in Los Angeles around 3:30 Saturday afternoon.  She was declared dead around 4pm PST, after paramedics spent 20 minutes trying to revive her.   The cause of death has not been determined.

Houston was in L.A. to perform at the pre-Grammy party held at the Beverly Hills Hotel each year by Clive Davis.  Davis, the founder of Arista Records, was Houston's mentor.  Dozens of media outlets, in town for the Grammy's, reported seeing Houston earlier this week greeting people with a warm smile but her hair appeared to be dripping wet with either sweat or water and she was poorly dressed wearing mismatched clothing.

Friends say her ex-husband, Bobby Brown, founding member of the group New Edition, was "beside himself", when informed of his ex-wife's death.  He was scheduled to perform with the group in Memphis, Tennessee, when he learned of her death.  He went on with the concert.

Neil Portnow, president of the Recording Academy, issued a statement about Houston and her contribution to the world of music and the academy.

“Six-time Grammy winner Whitney Houston was one of the world's greatest pop singers of all time who leaves behind a robust musical soundtrack spanning the past three decades.  Her powerful voice graced many memorable and award-winning songs. A light has been dimmed in our music community today, and we extend our deepest condolences to her family, friends, fans and all who have been touched by her beautiful voice.”


Houston is well known for her top 10 hits "I Will Always Love You", "Saving All My Love For You", and "How Will I Know".
