*Whitney Houston’s daughter Bobbi Kristina will start receiving portions of her $20 million inheritance from her mother and family members of the late singer are worried.

Bobbi Kristina will receive 10 percent of her mother’s $20 million estate ($2 million) when she turns 21 on March 4, another 6 percent when she turns 25 and the remainder of Whitney’s estate on her 30th birthday.

The National Enquirer reports that Whitney’s family are afraid that Bobbi Kristina’s new husband, her “adoptive” brother Nick Gordon, rushed her to jump the broom in order to get a piece of her pending fortune. To make matters worse, sources claim that Bobbi Kris did not have a pre-nup drawn when she married Gordon.

“The entire family is devastated over this marriage,” a source close to the Houston family said. “Krissi’s relationship with Nick was never romantic until after Whitney died. The family feels that if Whitney had adopted Nick and left him an inheritance, he never would have pursued Krissi.”

Although Whitney took Nick in as a 12-year-old and acted as his guardian, the singer never formally adopted him. As a result, sources believe this is the reason behind the current situation.
