Whitney Houston Dead: Ex-Husband Bobby Brown 'Devastated' By News Of Star's Death

Whitney Houston's ex-husband Bobby Brown and her on/off boyfriend Ray J were among those left devastated by the singer's death on Saturday.

The How Will I Know hitmaker's body was discovered by her minder in her suite at the Beverly Hilton hotel, where she was preparing for mentor Clive Davis' annual pre-Grammy Awards party. She was pronounced dead just before 4pm on Saturday after emergency service officials had failed to resuscitate her.

Insiders close to Brown, whom Houston divorced in 2007 after 15 years of marriage, told TMZ.com that the singer and reality TV star was "in and out of crying fits" upon hearing the news on Saturday, prior to a New Edition reunion concert in Mississippi.

At press time, Brown was planning to continue with the show.

Meanwhile, a source close to Ray J, who was reportedly dating Houston at the time of her death, tells CNN.com, "Ray J is distraught and trippin' right now."
