Why He's Sexy: He's funny, he's confident, he's willing to let his wife have 100 animals and he's got a great smile... What's not sexy about Blake Shelton? The singer's often self-deprecating sense of humor makes him seem more accessible. Plus, he'll talk to just about anyone on Twitter, even if he is telling you something you didn't want to hear.
