Bobbi Kristina Brown and Nick Gordon are not related. That being said, Nick lived with Whitney Houston since he was 12 years old and she considered him her son. He is 22 now. That means he was living with Bobbi Kristina from the time she was 9. Now the pair are supposedly romantic. Does that seem weird to you or is that ok? Nick confirmed it in a Tweet and said they had grown closer. Considering they were making out and groping each other at a Target yesterday, then yes, that would be closer.
