Keith Urban Puts Dierks Bentley and Jason Aldean on the Spot

Jason Aldean and Dierks Bentley found themselves a little red faced at a recent concert in Virginia, thanks to their buddy Keith Urban.

Our friends at Country Music Tattle Tale report that Keith surprised Dierks and Jason by asking them to join him on stage for a collaboration on the Eagles' hit, 'Take It to the Limit.' The problem: Keith's tourmates didn't quite know all of the lyrics. Thankfully, they had a few minutes to rectify their situation, so Dierks wrote the lyrics on his forearm and Jason taped some printed lyrics to his mic stand. But did the audience notice the stars' little cheat sheets? Yep, because Keith called them out! Watch the funny video on Keith's road blog.
