Christina Aguilera Glams Up 2011 NBC Upfronts

Stepping out for a publicity appearance, Christina Aguilera was spotted at the NBC Network 2011-12 Upfront Presentation today (May 16).

The “Ain’t No Other Man” songstress looked fabulous in a black dress with white polka dots and red peep-toe heels as she hammed it up for the cameras.
