While Carrie Underwood was performing her cover of Randy Travis’ “I Told You So” at the Grand Ole Opry on Tuesday (6/7), one fan spotted her two young sons backstage “breakdancing” during the performance and filmed the boys’ antics while their mom sang.

If you look closely at the video, you can see in the center, just behind the drummer Isiah and Jacob do some dancing.

The fan posted a clip of the performance on Twitter. They captioned the post, “I took a few, but this was the best one! @carrieunderwood, I never would have pictured ITYS being a breakdancing song, but your boys stole the show!”

The fan posted another, writing, “Completely not phased [sic] by who their mama is…”
