Here we are: The next round of March Madness, PopCrush's annual month long competition to determine the most dedicated, loyal fanbase among all the biggest pop stars of today.

The battle kicked off on March 1 with twelve acts, and after over a week of intense voting, the playing field's been narrowed down to a Top 8 — and this round promises to be especially fierce.

Today, it's Adam Lambert and his ever-faithful Glamberts up against Girls' Generation's passionate Sones.

Last week, Girls' Generation went head-to-head against a fellow girl group, the UK's mighty Little Mix. The Sones ultimately prevailed over the Mixers, leading with 58.29% of the vote. Lambert's Glamberts, on the other hand, had a mighty competition themselves, warring against 5 Seconds of Summer's 5SOSFAM in the first round. The Glamberts won — but it was a close one, coming in at just 50.96% of the vote. Will they prove victorious for a second time?

It's time to decide: Place your vote below. This round ends on March 16 at 11:59 PM EST. Get to voting!
