It seems like more and more these days actresses are proclaiming themselves to be more than they appear - triple threats (actress/singer/dancer). Well Zooey Deschanel hasn't debuted as a dancer yet, but she's definitely added "singer" to her resume.
Deschanel is half of the folky duo She & Him, alongside former one-man-band M. Ward. Their songs are not exactly my style, but twangy and catchy, worth a listen. Or for a visual, check out their quirky music video for their single "Why Do You Let Me Stay Here."
