Whoa! Hollywood Life is reporting that Whitney Houston's daughter, Bobbi Kristina Brown, is in a relationship with her unofficial "adopted" brother, Nicholas Gordon. Say what?!

Bobbi Kristina, 19, was spotting smooching Gordon, 22 in Target near the Atlanta suburb where the pair reside in Houston's townhouse.

“Bobbi and Nick were in the music section and then all over the store,” sources told Hollywood Life. “Bobbi was kissing him on the mouth and holding hands. They were laughing and smiling and seemed SO happy.”

The spies added, “She was wearing a black short pencil bandage skirt with a black top and black knee high boots. Her hair and makeup were all done too, like she was going to go out on the town. He was in all black — black jeans, black shirt, earrings and a black wide-brimmed hat.”

Who is Nicholas Gordon? Few knew about him, but Houston took him in as a child and raised him as her own. He's always been close with Bobbi Kristina (though Houston never officially adopted him), and she reportedly was aware of his relationship with her daughter, giving them her blessing to co-habitate in her Atlanta home.

Bobbi Kristina has taken her mother's death extremely hard, being hospitalized twice and surrounded by whispers of rehab. We're not sure if these rumors are true, but if they are, we're glad to see her happy. Bobbi Kristina will appear in a special interview on Oprah's OWN network tomorrow (March 11).
