Legendary pop singer Whitney Houston was found dead Saturday at a Beverly Hills, California, hotel, officials said, CNN reports.

She was 48.

According to TMZ, hotel employees have revealed that the singer was found unconscious in her hotel room's bathtub.

The entertainer, whose incredible talent was discovered at an early age, was pronounced dead at 3:55 p.m. (6:55 p.m. ET) at the Beverly Hilton hotel despite resuscitation efforts, a police spokesman said.

Beverly Hills Police Lt. Mark Rosen said there were "no obvious signs of criminal intent" and that the cause of her death is being investigated.

Houston's bodyguard found her body, said Courtney Barnes, publicist for hip-hop artist Ray J, who was dating the pop diva.

Houston, whose hits included "The Greatest Love of All," died on the eve of the 54th annual Grammy Awards at the Staples Center in Los Angeles. She had performed as late as Thursday night at a pre-Grammy event in the area. A pre-Grammy party was scheduled Saturday night at the Beverly Hilton.

Music producer Jimmy Jam, after conversations with those heading up to Sunday's night show, told CNN that he believes the event will change significantly - including a tribute to the singer.

Houston’s self-titled debut album, released in 1985, sold 25 million copies worldwide. In total, she released seven albums and three film soundtracks; a winner of six Grammys, Houston sold over 200 million albums and singles worldwide. She earned 30 Billboard Awards, 22 American Music Awards and two Emmy Awards.

MTV reminds that Houston had recently staged a comeback in 2009, after a tumultuous divorce from singer Bobby Brown in 2006 after 14 years of marriage. The ex-couple have a daughter together, Bobbi Kristina. Brown and Houston battled substance abuse issues throughout their marriage, and their travails were well-publicized. But in recent years, Houston had made attempts to revive her once thriving music career only to find that her show-stopping voice had gathered some rust.

According to Huffington Post, Bobby Brown took to the stage just hours after Whitney Houston's death, amid reports that the late singer's ex-husband was devastated by the news of her passing.

Brown was scheduled to perform in Mississippi as part of New Edition. The controversial R&B star was said to be in "crying fits" over the news, and broke down shortly after taking the stage.

"First of all, I want to tell you that I love you all,” he said to the crowd. "Second, I would like to say, 'I love you Whitney.' The hardest thing for me to do is come on this stage."
