With all the excitement about the new album/video/tour...I haven't seen anything about this, but maybe I missed it. The CMT Awards are tonight, and Grace and Kenny are up for awards:
"Meanwhile, Kenny Chesney and Grace Potter's "You and Tequila" is in the video of the year category, as well as the collaborative video category."
Grace just tweeted about being there and I think Kenny Chesney is going to perform tonight, but I haven't heard about a duet...we can hope.
Good luck Grace!
