Nick Gordon and Bobbi Kristina Brown

After an on-again, off-again relationship, Bobby Kristina Brown and Nick Gordon have gotten married. Whitney Houston's daughter shared a picture of their new wedding bands on Twitter Thursday.

Brown, 20, and Gordon, 24, first announced their engagement in an October 2012 episode of The Houstons: On Our Own, but it was called off one month later. "Were not engaged or dating," Gordon, who was partially raised by Houston, tweeted at the time. "Just close like we have always been."

In July 2013, Brown happily announced that the engagement was back on through her Facebook page. "YES, we me nick are engaged. 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,'" 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. My mom knows me better than any of you."
