Edie, Gary’s grandma, was remembering that when she was young, she competed in a dance contest in the 1950s. So she gets to dance on “Shake It Up, Chicago” in a special performance!

The episode is called “Rock ‘N Roll It Up” and it’ll air this Sunday at 8:30 p.m. How cute are the stars’ 50s-inspired looks?
