With the upcoming Presidential Election less than two months off, celebrities are pulling out all the stops to support their favorite candidate. And last night (September 25), Christina Aguilera hosted a massive “Rock the Vote” shindig.

The “Ain’t No Other Man” songstress arrived at the Esquire House in the Hollywood Hills looking sultry in a black dress with a matching black jacket and knee-high black leather boots.

Later this fall, Christina will be releasing her greatest hits album Keeps Getting Better - A Decade of Hits exclusively through Target stores.

Hitting shelves November 11th, the album will include all of her singles, as well as two new tracks: “Dynamite” and “Keeps Getting Better.”
