One lucky 7-year-old got to shake it off with Taylor Swift Monday night: In a video on Swift’s Instagram feed, the pop star dances alongside Dylan Barnes, who enthusiastically performed “Shake It Off” in a video that went viral — and got Ellen DeGeneres’ attention.

DeGeneres had Barnes on her show last week, where he talked about how he’s been dancing for two years before breaking into a live performance of “Shake It Off.” Then he got to show off his moves with Swift herself days later: “Finally got to meet Dylan, the 7-year-old who passionately danced to Shake It Off on Ellen,” Swift captioned the Instagram video. “And this happened.”

See that video, as well as his appearance on Ellen, below.
