A male/female acoustic duet? I saw it on TV some time ago.?

I guess it was about a year to a year and a half ago. A young guy and girl (early 20s?), both playing guitars and singing alternating verses. The guy had a cool hat. Any thoughts on what this might be? I don't remember any lyrics but it was really catchy.

It's not Picture. Thanks though! It was more upbeat than that.

Kid Rock and Sheryl Crow singing "Picture"...maybe?
Here's the video:
