Whitney Houston's Daughter, Bobbi Kristina Announces Engagement, As Bobby Brown Reveals He's NOT Happy (PHOTOS)

Bobbi Kristina Brown announced her engagement to her adopted brother, Nick last week.

But it seems that the 20-year-old daughter of the late Whitney Houston has already pressed fast-forward to the honeymoon as she's been enjoying a very public PDA with her 'brother' fiance, Nick Gordon in the warm Florida water....showing off her shapely body, her engagement ring and her affection for 24-year-old Gordon on her summer break

Their relationship has been the subject of scrutiny and a fair amount of eyebrow raising since their mother passed away in February last year.

And so Bobbi tackled the scandal in the post on her Facebook page last Wednesday, see what she wrote after the cut...

And when TMZ spoke with Bobbi's dad, Bobby Brown about his daughter's engagement his response was rather strange...see an excerpt of the interview below:

TMZ Photog: "How excited are you for your daughter -- she's about to get married and stuff?"

Bobby Brown: "I'M NOT."

................................................

That basically sums up Bobby Brown's feeling about his daughter Bobbi Kristina getting engaged to Nick "He's Not My Biological Brother" Gordon.

Bobby made it clear he doesn't approve ... and reveals that Nick never even called him up to ask for her hand inmarriage.
