The choices for the Third Headliner for our Ultimate PopCrush Music Festival are absolutely unreal! It's truly a battle of the boy bands for billing at this fantasy musical celebration, but not without some stiff competition from the ladies as well!

One Direction, Big Time Rush, the Wanted and the Jonas Brothers are all amazing boy bands, but in this case, only one has the opportunity to reign supreme! The 1D guys are becoming quite the seasoned road veterans as they are currently on a 120-city world tour, so you know their live show would be amazing. Big Time Rush are a blast on their TV show and we would imagine that totally translates to the stage. That goes for the Wanted too! Have you seen the trailers for their reality show? Hilarity! Not to mention, the Jo Bros play their own instruments so you get eye candy and a different kind of show from a boy band.

Now, these boy bands have some stiff competition from some of the leading ladies of pop. Alicia Keys is as talented as the day is long. Her voice and piano chops are second-to-none, so seeing her live is a no-brainer. Then there's Katy Perry whose penchant for theatrics is matched only by her penchant for outrageous stage costumes. Avril Lavigne has a million sing-a-long and energetic songs that are sure to get any crowd moving, so why wouldn't you want to be part of it? Then there's Kelly Clarkson, whose voice and great personality makes for an amazing stage presence.
