Aguilera encourages fans to cast votes for upcoming US elections

London, September 27 : Christina Aguilera has encouraged fans to head towards the US polling stations for the upcoming Presidential elections.

The American pop and R and B singer showed up at the 'Rock The Vote' party at the Esquire House on September 25 to encourage the public to voice their opinion in the political ballot.

"Everyone that is able to have an opinion should let it be heard and should voice it," the Sun quoted her as saying.

However, the singer admitted that in the mean time she wouldn't mind if the fans popped in to buy her new single "Keeps Gettin' Better", which is set to hit the market on November 3 - a day before the US election.

Christina, who recently put up a splendid performance at the MTV Video Music Awards, is scheduled to release her greatest hits album of the same name in the following week.
