Lady Gaga's Little Monsters and Britney Spears' Britney Army are going head-to-head in the Round 2 of March Madness! Little Monsters dominated Katy Perry's KatyCats in Round 1 while the Britney Army just managed to squeeze past Adam Lambert's Glamberts in the first round. Who should win this round?

When Little Monsters go hard, they go hard. It looks like Mother Monster's fanbase is well on their way to (possibly!) scoring another huge PopCrush victory. (In case you forgot, Gaga won seven PopCrush Choice Awards earlier this year!) And since we know their dedication knows no bounds, we wouldn't be at all surprised if the Little Monsters once again propelled their way to success -- after all, they're a seriously hardcore bunch. Paws up!

Britney Spears' Britney Army has been with her for every generation of Britney there's been. That's almost two whole decades of dedication! Seriously, the Britney Army has been loyal to their queen since the days of "…Baby One More Time" straight through to her Vegas show, always there to fawn over the singer and support her every move. Of course, this relationship isn't just one-sided -- Britney herself has more than proved her own dedication to her fanbase, even going so far as to write a heartfelt letter to a young gay fan who detailed how being a fan of hers changed his life.

Which fandom is most deserving of the Best Fanbase title? You can vote for Little Monsters or Britney Army once per hour until the poll closes on Tuesday, March 24 at 3PM ET. The winner of this round is one step closer to being crowned Best Fanbase!
