Whitney Houston

Los Angeles (CNN) -- Legendary pop singer Whitney Houston was found dead Saturday at a Beverly Hills, California, hotel, officials said. She was 48.

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.

According to her official website, Houston sold more than 170 million albums, singles and videos. But she also struggled with addiction problems over the years.

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.
