Bobbi Kristina, Whitney Houston’s daughter, rushed to hospital after Ray-J left Beverly Hilton Hotel

Whitney Houston’s daughter, Bobbi Kristina, was reportedly taken to hospital today just hours after her mother was found dead in a hotel bathroom.

Bobbi Kristina, 18, was rushed out of the Beverly Hilton hotel on a stretcher at around 10:30 a.m. this morning. She was reportedly suffering from anxiety after learning of the devastating news.

It comes as the first picture emerged today of Whitney Houston’s on-off boyfriend Ray-J leaving the hotel with his head in his hands, completely distraught.

Whitney Houston drowned alone in a bathtub having accidentally overdosed on a cocktail of prescription drugs and alcohol after two back-to-back evenings of out-of-control binges, it has been claimed.

The singer was found dead under the water by her bodyguard in a luxury hotel suite said to have been littered with bottles of prescription pills. She was 48.

Ray-J mentioned “missed calls” from Whitney Houston, according to the International Business Times, adding: “We all gotta live with that.”

Paramedics battled to revive the singer but she was pronounced dead at 3:55 p.m. yesterday afternoon, hours before she had been due to perform at a pre-Grammys party at the Beverly Hills Hilton in LA.

At first it was thought that Ray-J had found Whitney Houston’s body but a statement was later released by his spokesman saying “he was nowhere near the scene but no less distraught”.

According to reports on gather.com moments before the news broke, Ray-J was seen trying to console Bobbi Kristina, who was screaming, in the lobby of the hotel.

The singer/reality TV star and Whitney Houston dated between 2007 and 2009 but it was believed they had recently picked up their romance after being spotted at an LA restaurant.

Ray-J, 17 years younger than Whitney Houston, is the youngest brother of the singer Brandy and made a sex tape with Kim Kardashian in 2003 which was reportedly “leaked” on to the Internet.

Bottles of Lorazepam, Valium, Xanax and a sleeping medication were found in the hotel room, it has been claimed. The drugs were believed to have acted as sedatives, causing her to fall asleep in the bathtub once they had been mixed with alcohol from the previous evenings.

An autopsy is to be carried out today, according to TMZ, but the results will be delayed as toxicology tests must also be run.

Her frantic daughter Bobbi Kristina is understood to have got into a “furious screaming argument” with authorities who refused to let her into the hotel room to see the body of her dead mother. Friends of Whitney Houston’s cousin Dionne Warwick, who also went to the hotel to try to see the body, have said that she is “inconsolable”.

Police also turned away Ray-J from Whitney Houston’s suite on the fourth floor after he raced from his home following news of her death, reported TMZ.

Whitney Houston’s body remained at the hotel today where her family, including her daughter were paying their last respects, according to RadarOnline. Last night around 800 guests attended a pre-Grammys dinner at the hotel where Whitney Houston died.

Outside, fans gathered to mourn the star, leaving floral tributes and lighting candles.

The exact cause of death was not yet known. But on the Thursday evening before her death, Whitney Houston went on a wild binge in which she is said to have clashed with security guards. The next evening she “partied heavily, drank and chatted loudly” with friends at the hotel bar, claims TMZ.

According to Forbes, the night before Whitney Houston’s death, a hotel guest on the third floor beneath where the singer’s suite of rooms were located, had complained that water was pouring into his bathroom around 2:30 a.m.

Police have begun searching the hotel room for any signs of illegal drugs. The circumstances of the death are not thought to be suspicious but the authorities are investigating.
