Our second round grudge match features two '90s pop stars: Christina Aguilera and Beyonce. In the past few years, Christina has made a major comeback from her "Genie in a Bottle" days! The singer's recent stint as a judge on "The Voice" shows there's more to her than powerhouse vocals. On the other hand, there's no denying that this is Beyonce's year. Her incredible Super Bowl halftime show and touching HBO documentary prove that there is no stopping Queen B.
Who do you think should win round two of our "Most Influential Woman in Pop" March Madness bracket? Vote below ... and check back on Wednesday (March 6) to see the next two divas battling it out in round three.
