(500) Days of Summer co-stars Zooey Deschanel and Joseph Gordon-Levitt have a question for you — What are you doing New Year's Eve?

Zooey and Joseph posted a YouTube video of their duet of Nancy Wilson's version of "What Are You Doing New Year's Eve" on Dec. 28, and it's adorable. 

"I have known Joe Gordon-Levitt for going on 12 years," Zooey says of The Dark Knight Rises star on her website, HelloGiggles.com. "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. 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," the New Girl star, who was just nominated for a Golden Globe, adds. "But in the meantime, we made a little New Year’s duet for all of you!"
