Gwen Stefani was performing at a CMA After Party. In the video posted below on Twitter from SDGalGina- I love how Gwen Stefani kind of acknowledges the fact that it's kind of weird that she's playing music at a CMA After Party, but she does go on to day "We all have one thing in common, and that's that we love Blake Shelton!" She's so right! :) Check out their duet of Hella Good below!
