Bobbi Kristina Brown and Nick Gordon may have secretly married, the Daily News reports.
The 20-year-old daughter of the late Whitney Houston on Thursday tweeted a photo of the couple’s wedding bands.
"@nickdgordon #HappilyMarried SO#Inlove if you didn't get it the first time that is," she wrote in the picture of the couple's hands.
The pair's relationship has raised questions because Houston adopted Gordon when he was 12 years old. While the pair grew up together, Brown took to Facebook to respond to critics.
"Yes, me and Nick are engaged. 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?' " she wrote.
"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."
The couple announced their engagement in October 2012 before their brief reality TV show, The Houstons: On Our Own. After that, the engagement was called off briefly, but Brown announced this summer that it was back on again.
