Clint Eastwood had better watch out -- he might not hold the title of "most popular" at a political convention for much longer.

Mitt Romney might have pulled out his trump card by inviting the actor to speak at the Republican National Convention -- but, as it turns out, President Obama has some tricks up his sleeve as well.

It has just been announced that Natalie Portman, Scarlett Johansson and Kerry Washington will take the stage at the Democratic National Convention right before the POTUS announces his acceptance of the Democratic party's nomination on Thursday night. (Also scheduled to speak before President Obama are The Foo Fighters and Eva Longoria.)

Not only are we excited to see these celebs ... we're psyched to see what types of furniture they might pull onto the stage with them!

DiD yOu KnOw? ... President Obama has an impressive number of supporters, including fashion designers, athletes and actors. There's even a Wikipedia page listing all of them, which you can find, here.
