Fifth Harmony debuts new song 'We Know' live at Billboard

By Trey ·

A week or so ago, Fifth Harmony stopped by the Billboard headquarters at New York City and now we finally have the video!

The girls performed the acoustic version of "BO$$" again and also debuted a new track called "We Know."

"We Know" sounds like a hip-hoppy ballad in the style of Destiny's Child. This could be very promising on the album.

Let's go 5H!

Check out both performances below:
