You wanna know what I think? I think I'm sick of this question being asked. It answers it's self, I mean seriously come on. Would a gay guy sing all about girls and having relationships with girls? NO! Of course not that's stupid and doesn't make sence. So obviously he's NOT GAY!
Stop asking this stupid ass question guys and use your brains to think things through. That's why God gave it to you.
No hes not gay or bi. and even if he was would it really matter?? people should be judged by how they treat other people and who they are inside. not who they like or what gender they like. ok. so just quit judging him by wether hes gay (even though hes not) or not. ok? ok. and for all the girls that only like him bc hes hot get over it. think about whats inside. not every thing outside.
