What girl doesn't go crazy over a hot boy band? The guys of Glee have formed their own hot boy band, and they're singing the One Direction hit, "What Makes You Beautiful." Take a look at this totally swoonworthy sneak peek of Tuesday's Season 3, Episode 19: “Prom-asaurus.” Our favorite part is when each of the guys introduce their boy band alter-egos. These guys have got sideways looks and smoldering glances down to a science!
