She may be making a million an episode -- but that doesn't mean Kaley Cuoco doesn't know how to get down and dirty when her car gets a flat tire.

On Tuesday, Kaley, who earns a whopping $1 million per episode for her hit show The Big Bang Theory, hit quite the snag in the road when the tire of her new 250,000 new Mercedes SLS got a nail. The can-do actress stopped at a local gas station to seek help for her flat. Of course the down-to-earth star got in there -- trying to see what went wrong with her pricey ride.

Outfitted in gray sweats, a star-patterned t-shirt and hiding her cropped 'do with a baseball, at least the 28-year-old millionaire got to be comfy for her unscheduled event.
