In a new homemade video, the "New Girl" actress and "50/50" actor flex their vocal chords and their string instrument-playing skills in a cute duet of the song, "What Are You Doing New Year's Eve?"
Gordon-Levitt, 30, and Deschanel, 31, starred together in the 2009 flick "(500) Days of Summer."
Deschanel, who sings as part of the duo She & Him, played the role of blonde-haired songbird Jovie in 2003's "Elf" opposite Will Ferrell.
Gordon-Levitt also has a musical background -- he started hitRECord.org, an online collaborative production company that shares its profits with contributing artists, in 2004.
Watch their duet and tell Us if you think the pair should make more music together!
