The daughter of the late singer posted a picture of the pair holding hands, showing off what appeared to be wedding rings, with the caption: “‘#HappilyMarried So #Inlove if you didn’t get it the first time that is.”
Bobbi Kristina, who was just 18-years-old when her mother died on February 11 2012, got engaged to Gordon in 2012.
She was forced to defend the relationship on Facebook after their engagement was revealed to the world in reality show The Houstons: On Our Own.
“I’m tired of hearing people say ‘Eww you’re 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 she knew that we were going to start dating.”
The pair met when Whitney cared for Nick as a child.
The 20-year-old went on to defend her relationship insisting she wasn’t doing anything wrong.
She also called on people not to pass judgement on the couple and their romance without knowing all the facts.
