New fears for BOBBI KRISTINA BROWN family as hated hubby NICK GORDON may make off with her inheritance – sources. 

It’s double heartbreak for Whitney Houston’s family – as relatives fear that Bobbi Kristina’s hated hubby will inherit Whitney’s entire $20 million estate! 

As the sole heir to her mother’s fortune, Bobbi Kristina “didn’t protect herself with a prenup” when she married Nick Gordon in January 2014, The National ENQUIRER previously reported.

Nick has bitterly feuded with Whitney’s family ever since, with family members viewing him as “a gold digger and drug enabler for Bobbi,” said an insider.

 Bobbi Kristina’s father Bobby Brown has even denounced Nick’s marriage to Bobbi as a sham, saying the nups were never legal.

Tensions exploded last year when Whitney’s nephew Gary Houston beat up Nick “for being disrespectful to the family,” according to sources.

Nick entered Whitney’s life in 2008, after his stepfather kicked him out of their Georgia home because of his marijuana habit.

The singer unofficially adopted Nick – and The ENQUIRER reported in 2012 that he was dealing drugs to both Whitney and her daughter.

The gun-toting Nick has also been accused by neighbors of making death threats and carrying on all-night parties fueled by drugs and booze.
