Just weeks after the death of her mother Whitney Houston, Bobbi Kristina has allegedly gotten engaged. The fiancé is a little surprising–  it’s Kristina’s adopted brother Nick Gordon.

Nearly 10 years ago, Houston took in the then 12-year-old Gordon after he was having family troubles and immediately began calling her his. She raised him in the same home has Kristina was raised, whom began living as Gordon’s sister when she was merely 8-years-old.

Now Kristina’s grandmother, Cissy Houston, is stepping out saying what we’re all thinking, that “What [Bobbi and Nick] are doing is incestuous.” Well yeah, he’s her brother!

Unfortunately for Cissy (and the rest of the world), Kristina has been walking around sporting a big ol’ diamond engagement ring!

So are the almost-brother-and-sister really planning on walking down the isle?

Friends close to the pair have been claiming that although the pair have no official plans, they have been telling friends they’re headed to Vegas in the very near future.

What do you think? Is Bobbi Kristina going to elope with her brother? What would Whitney think?!
