Celebrities join final push for Barack Obama and Mitt Romney

From producers, actors to writers and a number of musicians, everyone is taking part in the campaign rally.

In Obama's blue corner, Bruce Springsteen is leading the campaign for the President alongwith celebrities like Harvey Weinstein, George Clooney, Madonna, Katy Perry, Pearl Jam, Jay-Z, Beyonce, Kathy Griffin, Cher, Chris Rock, Neil Diamond, Julianne Moore, Eva Longoria, Will Ferrell, Jennifer Lopez, Scarlett Johansson and Tyler Perry.

Perry appeared at an Obama event recently dressed in a tight blue PVC dress which featured the Democratic logo.

Singer Neil Diamond, who is working the phones for the Obama campaign, posted a picture on Twitter to prove to potential voters that he may really be on the other end of the line.

Legendary singer Stevie Wonder gave a surprise concert at a packed rally for Obama in Cincinnati. He also made an unannounced visit to Cleveland, where he did a street concert for a small crowd of 50 people near the busy Cuyahoga County early voting site.

The President also got the backing of comic actor Will Ferrell, who made a hillarious video asking people to go out and vote for Obama.

In the red corner, Mitt Romney and running mate Paul Ryan have their fair share of famous fans including Clint Eastwood, Kid Rock, Kelsey Grammar, Chuck Norris, Honey Boo Boo, Meat Loaf, Donald Trump, Jack Nicklaus and country music stars the Oak Ridge Boys and Lee Greenwood.

In August, Eastwood was a 'surprise' addition to the Republican National Convention. The 'Dirty Harry' star made a bizarre speech by addressing an invisible Obama on an empty chair.

"It may be time for someone else to come along and solve the problem," Eastwood had said in his speech.

Rocker Meat Loaf pledged to do anything for Romney on stage but his rendition of Romney's favourite song 'America the Beautiful' last month became the butt of many jokes when it emerged the singer had not registered to vote in his home state.

Americans vote for their next president on November 6.
