A surprise guest took the stage during Dierks Bentley's concert during Chicago's "Windy City Smokeout." 12-year-old Evie, Dierks' oldest daughter joined him up on stage to perform his hit "Different For Girls." Most kids would be mortified to step on stage in front of such a large crowd but not Evie! She walked over next to her Dad and the two gave a beautiful performance! What a proud Daddy moment for Dierks Bentley!!!
