Watch Zooey Deschanel and Joseph Gordon-Levitt Sing an Adorable New Year's Duet

It's a "500 Days of Summer" reunion! Thankfully, it's out of character, or that could be awkward...

Zooey Deschanel and Joseph Gordon-Levitt have seemingly decided that we needed a little holiday cheer for New Year's Eve, and released this charming little YouTube video of the two of them singing a duet: "What Are You Doing New Year's Eve?"

You may have seen these two together in "500 Days of Summer" and witnessed a bit of musical talent in their karaoke scenes (okay, only a little). Deschanel also plays in a band, She & Him, and recently sang the National Anthem at the World Series. JGL has showed off his rock star side as well, including a recent Jimmy Fallon appearance playing some classic rock covers.

If this little gem isn't enough for you, you can see Deschanel every week on "New Girl" on Fox when it returns in January. Gordon-Levitt will be appearing in "The Dark Knight Rises" next summer. As for seeing the two of them together, as they were in "500 Days"... well, we'll just have to see.
