This one has us scratching our heads…because, huh?!?

It’s being reported that Whitney Houston‘s daughter Bobbi Kristina is engaged — to her “adopted” brother Nick Gordon. Although he was not legally adopted by the late singer, she took him in when he was just 12 years old. He’s lived with her ever since. It is not known when he and Bobbi began a romantic relationship, but after Whitney’s passing they went public with their relationship — after opening referring to each other as “brother” and “sister” in the past.

“The situation is beyond sad,” a source tells Us. “Whitney never formally adopted Nick, but he lived with her and Bobbi Kristina from the age of twelve and they were raised like brother and sister. Nick came from a really bad background.”

The source adds that they were “always close” and their relationship “has evolved a lot … and they are living like a couple.”

The two were spotted kissing in public earlier this week.  Today,  Bobbi Kristina was spotted wearing a huge diamond engagement ring on her left hand  — which once belonged to her mother.

“Bobbi Kristina is still so vulnerable since her mother passed away,” the source says. “But Nick has become like her rock.”
