Whitney Houston, who ruled as pop music's queen until her majestic voice and regal image were ravaged by drug use, erratic behavior and a tumultuous marriage to singer Bobby Brown, died Saturday. She was 48.
Beverly Hills police Lt. Mark Rosen told reporters outside the Beverly Hilton that Houston was pronounced dead at 3:55 p.m. in her room on the fourth floor of the hotel. Her body remained there and Beverly Hills detectives were investigating.
"There were no obvious signs of any criminal intent at this time," Rosen said.
Houston's publicist, Kristen Foster, said Saturday that the cause of her death was unknown.
Rosen said police received a 911 call from hotel security about Houston at 3:43 p.m. Saturday. Paramedics who were already at the hotel because of a Grammy party unsuccessfully tried to resuscitate the singer, he said.
Beverly Hills Police Department later issued a statement:""Whitney Houston was pronounced dead that the scene by members of her entourage which included friends, co-workers, and family. Ms. Houston's daughter and mother were notified of here death."
The statement also added that "the investigation is currently being conducted" and that "there is no additional information at this time."

Houston's death came on the eve of music's biggest night -- the Grammy Awards. It's a showcase where she once reigned, and her death was sure to cast a heavy pall on Sunday's ceremony.
Her longtime mentor Clive Davis was to hold his annual concert and dinner Saturday, and a representative of the show said it would proceed.
Houston was supposed to appear at the gala, and Davis had told The Associated Press that she would perhaps perform: "It's her favorite night of the year ... (so) who knows by the end of the evening," he said.
Producer Jimmy Jam, who had worked with Houston, said he anticipated the evening would become a tribute to her, and he expected there to be one at the Grammys as well.
