Zooey Deschanel posted on her YouTube account the cute music video below of herself and fellow 500 Days of Summer co-star, Joe Gordon-Levitt.

In the video, the beautiful duo perform an acoustic version of Nancy Wilson’s song What Are You Doing New Year’s Eve? To introduce the video, Zoey wrote, “I have known Joe for going on 12 years. We first met in the summer of 2000 while doing a tiny movie called Manic, where we bonded over a mutual appreciation for Harry Nilsson and Nina Simone and I have been lucky enough to call him one of my dearest friends ever since.”

Zooey continued,  “When we did 500 Days of Summer 8 years later, we spent every lunch hour dancing to Marvin Gaye in the hair and make up trailer; we had loads of fun. I hope to do a thousand more movies with him because he’s simply the best. But in the meantime, we made a little New Year’s duet for all of you! The original by Nancy Wilson. ENJOY!”
