Rumors are flying on Twitter that Clint Eastwood will make a surprise appearance on Thursday at the convention.

Right-leaning magazine Townhall reports on their blog that a "well-placed" Republican source confirms that the movie star will be going to the convention, though they could not say if he would be speaking to the delegates.

If he is speaking, he'll take the stage just before Sen. Marco Rubio (R-Fla.) introduces Mitt Romney.
