Bobbi Kristina Engaged…

Bobbi Kristina, the 19 year old daughter of Whitney Houston and Bobby Brown, is secretly engaged… To her adopted brother.

She’s agreed to marry Nick Gordon, a longtime friend that’s known as her adopted brother. Nick was never formally adopted by Whitney but she raised him like family after his father was sent to prison many years ago.

A source told Star Magazine, “Nick proposed to Krissy on March 10, and she said yes. Krissy said Nick is the only person she trusts in the world. They have a very deep connection.”

Currently, Bobbi Kristina and Nick are living together in Whitney’s $1.2mil townhome in Atlanta, and they call each other brother and sister.

Bobbi’s family said that he’s always been protective of her, but they are scared of his intentions since she just inherited a $10mil fortune.

A friend of the family told the magazine, “She’s taking prescription pills and saying things that make her family feel she’s suicidal. Nick is getting her at her most vulnerable. If he really loved her, he’d back off the engagement and just be her friend.”

Bobbi Kristina’s grandmother, Cissy Houston, has weighed in after seeing pictures of the newly engaged couple kissing and holding hands in public. She said, “What they are doing is incestuous.” She says that Bobbi is impressionable and an easy target. She plans on taking legal steps to get him evicted from Whitney’s home.
