Whitney Houston's daughter's £1 billion inheritance could kill her

Bobbi Kristina will inherit £1 billion from her late mother, but her well-wishers fear that all the cash could prove deadly for her.

Experts have valued the “Whitney brand” at the huge sum, including record sales, stage shows, films and merchandise and Bobbi Kristina, 19, will get the fortune.

Houston’s ex-husband Bobby Brown, 43, signed a pre-nuptial agreement that means he will not inherit any of it.

Now, frantic relatives are afraid the massive riches could send the late singer’s drug-taking teenage daughter into meltdown.

They fear Bobbi, seen in new pictures smoking a cannabis bong and apparently snorting cocaine, will blow the money on drugs. They want to limit her access to her mum’s estate.

Troubled Bobbi has been rushed to hospital at least twice after downing booze and pills to cope with her grief.

“This amount of cash for any teenager could spell trouble.

“But for Bobbi Kristina, who has been partying hard for years, it could spell disaster,” the Daily Star quoted a family pal as saying.

An ex-boyfriend sold the pictures of her at the age of 17 at a party near her mum’s home in Alpharetta, Georgia.

“I tried to stop her. But she said: ‘I’m just like my mum!’

“If Bobbi doesn’t stop, cocaine will kill her,” he said.

US brand manager Grant Cardone on Sunday dismissed reports Houston’s estate was worth “just” £100 million.

“Whitney as a ‘brand’ could be worth £1 billion.

“There is huge money to be made from Whitney-themed movies, plays and Vegas shows,” he said.

Bobbi will open her heart about her drug use and grief to Oprah Winfrey, 58, on US TV this Sunday.

Houston was found dead in a bathtub at the Beverly Hilton hotel, LA, in February, aged 48.
