Bobbi Kristina Brown is set to marry Nick Gordon against Cissy Houston’s wishes

Bobbi Kristina Brown is set to marry Nick Gordon despite grandmother Cissy Houston branding their relationship “incestuous”, new reports claimed today.

Bobbi Kristina Brown, 19, is said to be totally disregarding Cissy Houston’s wishes, who has slammed her relationship with Nick Gordon as “incestuous”.

A source told Star magazine: “Krissy has told her grandmother that she doesn’t need her blessing to marry Nick, and the more Cissy objects to the relationship, well that only cements Krissy’s decision.

“It’s just a very sad situation. Clearly, Krissy loves Nick, but she has just lost her mother, and her entire world has been turned upside down. Krissy doesn’t think she needs to wait, and points to her mom’s sudden death as the reason to marry Nick.”

Meanwhile TMZ reports that Bobbi Kristina is not listening to her grandmother and the website reports she is telling friends she doesn’t care what her family thinks.
