Bobbi Kristina Brown, 23, took to Facebook Tuesday night to clear up some things about her relationship with Nick Gordon.

First, after a year of denying the rumors, Whitney Houston's daughter, the star of "The Houstons: On Our Own," confirmed she's engaged to Gordon.

She also said that the two are in no way related.

"Let me clear up something, we aren't even real brother and sister nor is he my adoptive brother," Bobbi Kristina Brown wrote on her wall.

She added that her late mother actually predicted the two would start dating and was completely fine with it.

"People need to seriously stop judging my relationship," she wrote. "Pretty sure it's my own decision who I want to be with."

She closed her social media message by saying her relationship in no way would be affected by outsiders.

"Judge me, go ahead," she said. "It is my life and not yours. The decisions I make have nothing to do with you."
