This time it’s for real.

Bobbi Kristina Brown is engaged to Nick Gordon, more than a year after her rep denied rumors the pair was set to tie the knot.

But Whitney Houston’s 23-year-old daughter wants to make one thing known: She’s not keeping it all in the family.

“I’m tired of hearing people say, ‘Eww your (sic) engaged to your brother’ or if Whitney was still alive would we be together or would she approve of this?” Brown wrote on her Facebook page Wednesday. “Let me clear up something, we aren’t even real brother and sister, nor is he my adoptive brother. My mom never adopted him.”

Brown is confident that her late mother would give the pair’s marriage plans her stamp of approval.

“Mommy was the one who even said that she knew that we were going to start dating,” she wrote. “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.”

But despite her joy – which was also expressed on Instagram – Brown acknowledges that the road to engagement has not been without its bumps.

“Yes, my relationship may not be perfect,” she said. “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.”
