Christmas is over, but kids lip syncing to holiday songs can still bring joy to the world. Especially this one.

On Thursday afternoon, Larry King tweeted this adorable footage of his toddler nephew soulfully mouthing the words to Josh Groban's rendition of "Angels We Have Heard On High." The video was uploaded to YouTube by the little boy's father, Ryan Engemann.

"Maybe I'm biased b/c he's my nephew but this has to be the cutest @JoshGroban cover I've seen," King wrote of 2-year-old Gavin's performance.

And he wasn't the only one to offer praise. Josh Groban himself replied to the tweet, saying the video "made [his] day." Of course, Groban later added an important clarification.
