John Mayer and Keith Urban plugged in and jammed out at a sound check for tonight's 2010 CMT Music Awards earlier today.
The two, who recently filmed an episode of "Crossroads" together, will be performing the song "Hit the Ground Running."
Mayer canceled shows in Europe last month due to illness -- but by the look of these sneak peek pics, tonight's show is gonna rock... in a country kinda way.
