There's no denying that Mark Ronson's "Uptown Funk," which uses the suave vocals of Bruno Mars, was the grooviest song of 2014. With those horns, that bass line and punctuated vocals, all it needed was a few hair flips to make it into the sassiest cover Fifth Harmony has ever done.

The ladies of 5H brought together their newly announced tourmates for their cover of the '70s-inspired track. And guess what? There are plenty of hair flips.

The girl group is going on tour with the help of MTV. And along with having them in this video, 5H are bringing along Jacob Whitesides, Jasmine V, and Mahogany Lox for The Reflection Tour.
