Bobbi Kristina kissing adopted brother Nick Gordon - Photo

Bobbi Kristina Brown tweeted a picture of her kissing her adopted brother Nick Gordon on the lips the other day. "It's just US now," she wrote.

Whitney Houston unofficially adopted Nick over 10 years ago. I wonder what she would have thought of this relationship.
