Whitney Houston Daughter Bobbi Kristina Engaged to Step Brother Nick Gordan [PHOTOS]: Troubled Teen Announces Plans for Marriage Via Facebook

Whitney Houston may be turning in her grave at the news of her only daughter Bobbi Kristina, 20, and her stepson Nick Gordon's engagement.  Bobbi announced her plans to marry her stepbrother who was raised with her as Whitney took him in at the age of 12.

In a heartfelt explanatory message to her fans Bobbi Kristina revealed that she was engaged and that her late mother Whitney Houston would approve.  Bobbi wrote:

"YES, we me nick are engaged. I'm tired of hearing people say "eww your engaged to your brother or if Whitney was still alive would we 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 yall are saying that yall 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"

Bobbi and Nick's relationship was made public shortly after Whitney's untimely death.  The couple even showcased their love for one another on the Houston family reality show, "The Houstons: On Our Own."  Bobbi Kristina revealed to her family on the first episode October 2012 that she and Nick were engaged.  The Facebook post seemed to be geared towards "haters?" 

While no wedding date has been set Bobbi and Nick will probably make another announcement when it all goes down.
