Whitney Houston's Daughter Bobbi Kristina "Happily Married"

Who knew?!

Whitney Houston's daughter Bobbi Kristina Brown announced on Twitter Thursday that she and Nick Gordon got secretly married, and she shared the news by posting a picture of their wedding rings.

"@nickgordon! #HappilyMarried. SO #Inlove," she captioned the snapshot.

The young couple was previously engaged in October 2012, but called it off one month later amid reports that Brown's family members didn't approve of the union. The reason? Houston reportedly informally adopted Gordon when he was 12-years-old, so he and Bobbi Kristina had been living together basically as brother and sister for a number of years.

"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 of 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 that she knew we were going to start dating," she wrote on Facebook at the time.

We guess congrats?
