Whitney's Houston's daughter and "son" are in love — and getting married!

Bobbi broke the news — that she and boyfriend Nick Gordon will be tying the knot — on Facebook early this morning, July 10, on Facebook.

"Yes we … are engaged," the late pop diva's 20-year-old daughter writes.

Bobbi Kristina's romance with Nick has been a point of controversy ever since Whitney referred to him as her "son." But Bobbi wants to put that talk to rest once and for all.

"I'm tired of hearing people say, 'Ew, you're engaged to your brother,'" she writes, "Or, 'If Whitney was still alive, would [you] be together?' or 'Would she approve of this?'

"Let me clear up something: We aren't even real brother and sister, nor is he my adoptive brother. MY mom never adopted him. In fact, Mommy was the one who even said that she knew that we were going to start dating.

"My mom knows me better than any of you. A lot of y'all are saying that y'all are only saying this all out of love. Which is bull because if that was so, all you would want is for me to be happy.

"People need to seriously stop judging my relationship. Pretty sure it's my own decision who I want to be with. Yes, my relationship may not be perfect. We will have rough patches, just like every other relationship. And we have had our rough patches. You may or may not agree with my relationship. You may or may not respect it. Judge me — go ahead. Your opinions are yours and mine are mine. It is my life and not yours. The decisions I make have nothing to do with you. Goodnight."

Wow, we really feel the love!
