Have Bobbi Kristina Brown and Nick Gordon finally tied the knot?
There's been no word of a ceremony, but Whitney Houston's daughter posted a photo on Twitter
of what appears to be the couple showing off their wedding rings.
"@nickdgordon #HappilyMarried SO#Inlove if you didn't get it the first time that is," wrote Brown, 20.
The couple got engaged
last summer, but their relationship has always been controversial.
Brown's late mother raised Gordon like a son, but Brown says she never adopted him and that the singer, who died in 2012,
would approve of their love.
"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 said last summer. "Let me clear up something, we aren't even real brother and sister, nor is he my adoptive brother. My mom never adopted him."
She added: "Mommy was the one who even said that she knew that we were going to start dating."
