Summer Fan Showdown is a month-long competition on PopCrush to determine this summer's most dedicated fan base.

This year's Summer Fan Showdown is kicking off, and today, we've got two wildly different acts going head-to-head in the first round.

First off, there's Miley Cyrus, our beloved post-Disney Hannah Montana princess, post-Bangerz tongue-happy rebel who's now found herself settling into her country side once again with her gorgeous new summer song, "Malibu." But whether wearing her Hannah Montana wig, twerking up against poles or simply admiring the breeze by the beach, her loyal Smilers have stayed along for the ride every step of the way. Will they keep her moving into Round 2 of the competition?

And then, there's TVXQ. The group might have gone on hiatus after both Yunho and Changmin went off for mandatory military service, but they're both due back on the South Korean music scene by the end of this year. With over 10 million records behind their name since their debut in 2003, the comeback after all this time is expected to be nothing less than massive. Will the Cassiopeia, TVXQ's fans, get their superstars into the second round of the Showdown?

The battle starts now: place your vote between Miley Cyrus and TVXQ. This round ends on June 9 at midnight.

This poll is now closed. Vote in Round 2!
