Whitney Houston’s family is planning to encase her body in concrete to prevent the stealing of the $750,000 worth of jewellery the late singer is buried with.

At the moment Whitney Houston’s grave is under 24-hour guard at Fairview Cemetery in New Jersey but it is thought her mother Cissy Houston can’t afford to keep up the security.

Whitney Houston was buried with a diamond brooch and earrings next to the body of her father John Russell Houston Jr. – who died in 2003 – in February.

A close family source told the Daily Star newspaper: “Cissy can’t afford to keep paying guards forever. A concrete encasement is the only answer.”

A burial expert at Hollywood Forever, which houses the remains of a number of celebrities, believes encasing Whitney Houston in concrete is a “sensible move”.

They said: “It makes robbery virtually impossible. It would take a long time to get through, even with a pneumatic drill.”

Cissy Houston, 78, has also announced she wants to set the record straight about her daughter, who was found dead in a bath tub at the Beverly Hilton hotel in February aged 48.

Whitney Houston’s mother has vowed to write a book publishing both the “good” and “bad” times in the singer’s life.

She is quoted by the New York Times as saying: “I want to stop the lies, It’s going to be the bad. It’s going to be the good.”

Cissy Houston has met a number of New York publishers about the tome, and she could reach a seven-figure deal depending on what she reveals about Whitney Houston’s drug issues and previous marriage to Bobby Brown.
