Nick Gordon and Bobbi Kristina Brown split?

Bobbi Kristina Brown and Nick Gordon have called time on their romantic relationship, new reports suggest.

The pair announced their engagement last month in a preview for her family’s upcoming reality show The Houstons: On Our Own, but the couple have now called off their relationship.

Nick Gordon, 23, tweeted on November 18: “@REALbkBrown and I are not engaged or dating. Just close like we have always been.”

Bobbi Kristina Brown later wrote: “Spending time together, sunday night football & Playing with our @nickgordon new 3DS’s! Soooooo… Goodbye !!(:(:(: (sic).”

The following week she also posted a number of cryptic tweets suggesting she is all alone.

She wrote: “I’m leaving , this this good ole town and driving to the send of the world . Maybe it’s beautiful there (: Xxxo. Who do I trust in this world? Pfft well that’s easy beezie, #Myself, No1 will kno’s me like ME&They’d rather not take thtchance2knoME, & 2me.”

Another read: “That’s incredibly fine .. Because you’d be missing out on a #REALperson Xxo #armyofme #onmywon #goingtomakeit#determined.”

“I guess it’s time 4me2stop depending on anymore. It’s my time2follow what Mom&The Lord put out on this path for me. #Thankful. Mom xxo (sic).”

At the time of the car crash, Bobbi Kristina Brown described herself as “Partner of @ndgordon” on her Twitter page.

Nick Gordon was informally adopted by Whitney Houston when he was 12 and the pair were raised as brother and sister.

They were “always close” growing up but their relationship changed as they got older and they sought comfort in each other after Whitney Houston’s death in February and started living like a couple.

Whitney Houston was found dead in a Beverly Hills hotel room on February 11, 2012.
