Whitney Houston, one of the world’s most popular singers, died this afternoon at a hotel in Beverly Hills after attempts to resuscitate her failed.

Houston's death was confirmed by her representative to the Associated Press. The singer was 48.

According to the initial reports, Houston was pronounced dead at 3:55 p.m. at the Beverly Hilton Hotel, People Magazine reported.

"It's unclear who notified hotel staff because she has quite an entourage here at the hotel. We attempted to resuscitate her, to no avail," Beverly Hills Police Lieutenant Mark Rosen told the magazine.

The singer was expected to perform at Clive Davis' annual pre-Grammy party later Saturday at the Beverly Hilton hotel. Davis is a renown veteran music mogul.

Whitney Houston's death is under investigation, according to the Lieutenant who said the police didn't know if there was any evidence of drugs or foul play.

Houston battled drug addiction for many years.
