On Thursday, Bobbi Kristina tweeted a pic of her and her beau sporting wedding rings, writing, "#HappilyMarried So #Inlove if you didn't get it the first time that is."
The 20-year-old, who ventured into reality TV with Lifetime's The Houstons: On Our Own, initially announced her engagement to Gordon, 24, in Oct. 2012, but subsequently called it off.
She again got engaged to Gordon -- who she often describes as a brother-like figure -- in July 2013, saying via Facebook, "YES, we me nick are engaged. I'm tired of hearing people say 'eww your engaged to your brother' or 'if Whitney was still alive would we be together or would she approve of this.'"
Some might be skeptical that the two actually wed, as Bobbi Kristina teased she'd tied the knot with Gordon in Nov. 2013, calling him "hubby" on twitter.
Next month will mark the 2-year anniversary of Houston's tragic passing, which subsequently launched her surviving daughter into the limelight.
