Whitney Houston, as famous for her golden voice as she was for the troubles that plagued her personal life, has died. She was 48.
Her publicist, Kristen Foster, confirmed the singer’s death Saturday only hours before Houston was due to perform at music mogul Clive Davis’s annual pre-Grammy party at the Beverly Hilton Hotel.
“I can confirm that Whitney Houston was pronounced dead at 3:55 p.m. at the Beverly Hilton Hotel. We received a call at 3:43 p.m. from hotel security and Beverly Hills fire and police responded minutes later,” Beverly Hills Police Lieutenant Mark Rosen tells PEOPLE.
“Someone in her entourage found her unresponsive in her room … 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.”
As to whether there was any evidence of drugs or foul play, Rosen responded: “At this time, there’s no obvious evidence of foul play or cause of death.”
Earlier this week, the six-time Grammy winner, whose record sales in the United States alone totaled 55 million, was spotted having a night out on the town in L.A. at “Kelly Price & Friends Unplugged: For The Love Of R&B Grammy Party” at Tru Hollywood.
