Pals Zooey Deschanel and Joseph Gordon-Levitt are triple threats: besides good looks, they can both act and sing!

In the homemade video above, the New Girl actress and 50/50 actor flex their vocal chords and their string instrument-playing skills in a cute duet titled "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, an online collaborative production company that shares its profits with contributing artists, in 2004.
