Dude, he is smoking hot and his personality on Hard Knocks was fantastic too. I confess to having a crush on him.
However, I went to USC at the same time he did...homeboy was notorious for slutting it up with the sorority girls there. He went through them left and right and it was pretty well documented (meaning people could give specific names if asked), not to mention it was well known that he cheated on one girl who he was dating with another one of her sorority sisters (once again, everybody at SC then knows the names/sorority).
I highly doubt the guy is gay. I know that some gay guys sleep with women to uphold a front, but the rate he went through them would be ridiculous even for that scenario. The most I would believe is that he was bi, but I highly doubt that even that. It's wishful thinking...but fun wishful thinking for sure.
