Surprise appearances by other musical acts and or celebrities other than the one the specifically paid to see are nothing new however to the concert goer these days, although it’s not all too common for the surprise guest to be romantically linked. Shelton joined Gwen on stage for a surprise duet of “Go Ahead and Break My Heart“, and the crowd ate it up. Blake Shelton even seemed to want to add in some lip sync battle style as he mouthed the words while Gwen Stefani sang.
