And he wasn’t exactly an invited guest.
Grunwald shocked the crowd by trotting out on stage wearing a sexy little flight attendant outfit to bring Dierks Bentley and his band a tray full of drinks when they were performing the set final song of the night, Drunk on a Plane.
Grunwald got all dolled up in the dress, makeup and heels and took the stage with a tray of Johnny Walker Red shots. Watching Grunwald walk in high heels was hilarious! This is not the first time either. Grunwald donned the outfit for the Downtown Hoedown a few years ago when Dierks was playing the show.
It was a hit!
