Ok...I'm a bit influenced because I'm a Jasper پرستار so for me Jasper is the hottest:P But honestly they are all very hot, sweet, cute and interesting:P
in the bk i think they r both hot(wid good personalities) and its hard to choose but between kellan and rob.., well kellan is waaaaaaaaaay Sm-hooottt!!!(btw i think rob is ugly, no offense rob fans) and besides, I am a big jasper fan!!!
emmett the actor is hotter than rob but in the book edward is portrayed much much hotter than edward. so if its between the actors, emmet is hotter if it is between the characters in the book, edward is totally hotter!! <3
