Maybe its just me but he usually says these things when Jen or Joe are around - maybe hes trying to annoy them or something? He doesn't seem "gay" to me. Or bi as some like to think. Or maybe im in denial ROFL!! He did have a girlfriend.
Then again look on his myspace - there is a pic of him flexing and it says "hey single guys of austraila". Sigh!
And Dani has a boyfriend, I really don't think shes going to screw that up. I read somewhere that he gave her "permission" to flirt and be catty (his words apparently, whatever that means) haha.
And I actually know alot of non gay guys that think some guys are hot. Maybe they wouldn't be as blunt as Nick but yeah. He could very easily be trying to get the gays votes. I don't know. I just don't see him as gay........ but who does know. He seems to really like Daniele.
