One Direction: Reportedly Using Ricky Martin and Dance Classes to Prep for Tour!

(There's nothing we love more than a passionate singer!)

(First up is Zayn, and he's putting some major emotion into it!)

(We're betting Louis had to gasp for a big gulp of air after this one.)

(Harry gives it all he's got. Look at that vein popping on the side of his neck!)

(Niall stands up straight to hit his high notes!)

(Known as the more serious one in the group, Liam not surprisingly is digging really deep.) 

(Looking very "in the moment," Zayn is surely giving the crowd their money's worth.)

(Louis really steps into this one! We're liking this.) 

(Harry may take the award for "most intense performer" in 1D!)

(Niall keeps it calm, cool and collected.)

(Still staying in serious mode, Liam makes eye contact with some lucky fan.)

(So once again...we can't decide on a favorite. Can you blame us? Just look at them!)
