*UPDATED 8.00pm Sunday* Whitney Houston's daughter, Bobbi Kristina, has now been rushed to hospital from the Beverly Hilton Hotel...

This should probably remain unsaid, but ever since I read last week that she was treading old ground again with ex-flame Ray J, I'd a lurking feeling something unfortunate was on the cards.  In this case, "unfortunate" is a bit of an understatement.

The 'My Love is Your Love' hitmaker was pronounced dead by paramedics at the Beverly Hilton Hotel at 3.55pm yesterday (11.02.12) after she was unresponsive to attempts at reviving her.

A reason for her death has not yet been given, and her body was identified by family and friends, TMZ.com reports.

Whitney was staying at the hotel ahead of a planned performance at Clive Davies' pre-Grammy party - which took place last night - and she was seen partying and drinking with friends on Friday night (10.02.12).

Hours after her death her 18-year-old daughter Bobbi Kristina - whom she had with ex-husband Bobby Brown - tried to see her mother's body but was denied access by police. Whitney's cousin Dionne Warwick turned up some hours later and she was also denied access.

Meanwhile a teary Bobby Brown took to the stage for a planned concert in Mississippi with his group New Edition. I too am surprised. At the end of one song, he looked skyward, where he blew a kiss and shouted: 'I love you, Whitney.'

Whitney and Brown were married from 1992 to 2007, and the pair were known for a volatile relationship that included periods of extremely heavy drug use.

However, speaking about their marriage in 2009, Whitney admitted she had strong feelings for him, saying "I loved him so much. He was my drug. I didn't do anything without him."

Jennifer Hudson will lead the tributes at tonight's Grammy Awards, "as the show executives scrambled to cope with the sudden death of the star."
