Britney Spears' Army vs. 2NE1's Blackjacks

"I am the best," the ladies of 2NE1 proudly proclaimed. "Living Legend, you can look but don't touch," said Brit Brit. Yep — this round of March Madness is gonna be a doozy.

We kicked off our annual March Madness competition to seek out the most passionate pop fanbase at the beginning of March, with 16 incredibly devoted fan armies going head-to-head against each other. Eight have prevailed to move on to the second round, which starts today (March 10).

Last week, Britney Spears beat out Rihanna's Navy with a whopping 80.03% of the vote — it was a landslide victory. On the other hand, the K-Pop Queens had a pretty solid round themselves, knocking Fifth Harmony out of the competition with a strong 67.42% of the vote.

Two super loyal fanbases. Only one will move ahead. Which will take it to the semi-finals, the Britney Army or 2NE1's Blackjacks?

It's time to vote. This round will end on March 16 at 11:59 PM EST. Go!

And while you're at it, vote between KatyCats and Directioners.
