Bobbi Kristina Goes Public With "Brother" Nick Gordon

Whitney Houston's daughter Bobbi Kristina and Whitney's "adopted" son Nick Gordon have gone public with their relationship. The two decided to show their love for one another at the 2012 Billboard Music Awards, where Bobbi Kristina watched a beautiful tribute to her mother.
Bobbi and Nick were raised as siblings from a young age and recently began dating. Sources close to the Houston family claim Nick and Bobbi have a close relationship, but are just friends. 
Well, that kiss sure seems...friendly?
