#1: BRITNEY SPEARS

What to look forward to this year: Although plenty of people would debate her topping the list, this year could potentially solidify Spears' legendary stature. Now that Lady Gaga is currently at the top of the pop world, we're looking forward to seeing Britney battle it out with the Fame Monster to prove her supremacy. With her first single, "Hold It Against Me," already topping charts and her highly-anticipated, currently-untitled new album (her first release since 2008's Circus) set to drop on March 15, Britney should remind us all that she is the princess of pop.
