After 4-year-old Claire and her dad Dave’s web video stole hearts around the world with more than 150 million views online, they came to Ellen’s show to perform their duet live!

Their cover, which was released via YouTube on January 17, already has over 7 million views — and for good reason. Not only are the two incredibly cute, but they’re super talented and, obviously, have a lot of musical chemistry.

Mimicking the setup they had for their home performance, 4-year-old Claire Ryann and her dad took a seat on the “Ellen” stage to perform the cover, and it was awesome.
