It looks like after the youngster’s dance routine went viral last month, Tay wanted in on the action!

"Finally got to meet Dylan, the 7-year-old who passionately danced to Shake It Off on Ellen--- and this happened," the country star captioned on the clip that she uploaded to her Instagram.

Taylor can be seen strutting her stuff across the floor while Dylan jumps around. Too cute!
