Mercury News reports, “Whitney Houston’s 20-year-old daughter secretly got married to the man her mother informally adopted when he was 12, according to Us Weekly.

This should last.

Bobbi Kristina Brown tweeted Thursday she and Nick Gordon are “happily married.” The daughter of the late Whitney Houston and Bobby Brown posted a photo of the couple’s wedding rings.

“@nickgordon! #HappilyMarried,” she captioned the photo. “SO #Inlove. If you didn’t get it the first time that is.” The picture shows Brown’s hand resting on top of Gordon’s hand, with their weddings bands on display.

Brown and Gordon announced their engagement in October 2012 during their short-lived reality show “The Houstons: On Our Own.”  The two reportedly called it off a month later, after Houston’s family made it clear they didn’t approve of the relationship. Gordon lived with Houston and her family throughout his teen years.

Brown announced in July 2013 they were engaged again. “Yes, me and Nick are engaged,” she wrote on Facebook. “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 that she knew that we were going to start dating.”

This is weird.

Bobbi Kristina also hinted on Twitter on Thursday she’ll have other news soon. “BIGGGG things in store guys . . . I’m so excited!” she wrote. “We bouta change the world babbbbby! #bringEmOut! #Getready! xO!”

Yes, they will most certainly change the world.

No comments yet from Houston’s family or from Bobbi Kristina’s father, singer Bobby Brown.”
