Bobbi Kristina's engagement mystery deepens

Washington, Mar 17 (ANI): Whitney Houston's daughter Bobbi Kristina has reportedly blasted her grandmother Cissy Houston's claims that her relationship with adopted brother Nick Gordon is "incestuous".

Bobbi, 19, was spotted with a ring on her finger following days of very public displays of affection with Gordon.

"Yes, they are engaged, but the family is trying to coax her away from it," People quoted an insider as saying.

Another source says, "Nick asked Krissi about a week ago to marry him" and she's wearing a ring that once belonged to her mom. But the source doesn't know if she said yes.

Bobbi and Gordon grew up as brother and sister after Whitney took him in when he was 10, as his own mother could not cope.

Since the singer's tragic death last month, the pair have become inseparable.

It is believed that Cissy is "disgusted" with the relationship but her granddaughter says they are "doing nothing wrong".

"I don't give a damn what Cissy thinks about our relationship. I couldn't care less. It's my life and I can do what I want, nobody is going to stop me seeing him," the Daily Star quoted her as telling a friend.

"He's not my blood brother, we are doing nothing wrong," she said. (ANI)
