PopCrush is celebrating pop music's most dedicated humanitarians in this round of our 2011 PopCrush Music Awards. Whether pop superstars were donating their time and effort towards a good cause or helping improve our world in general, all of our nominees did their philanthropic part in 2011.

Below, readers can cast their vote for the pop star whose humanitarian efforts really struck a cord with them. Polls will be opened until Jan. 1, 2012 at 11:59PM EST and we will announce the winners on Jan. 3
