It's a joke. I don't think they're brothers. It is a joke in very bad taste though. This Chris Crocker guy is the same one who went onto a talk show and said that both he and Britney were beautiful women. He goes for the shock value in order to increase his views on his videos.
What would be funnier is if someone met him in real life and found out that off the camera he acted totally butch and normal. I doubt that though. His sense of humor is just too immoral for him to be normal in any way.
