Last night on the Voice finale, pop fans got a huge surprise when Lady Gaga and Christina Aguilera performed a duet from Gaga’s latest album. The ladies tore down the stage with their amazing voices but we couldn’t stop staring at their hair! Both ladies went baby blonde but with drastically different styles and textures. Gaga opted for a chic and smooth bob with fringe, while Aguilera opted for voluminous babydoll curls. We have to say they both look AMAZING!!!
