Boyce Avenue & Fifth Harmony - Mirrors - Justin Timberlake Cover - Video

The X Factor's Fifth Harmony and rock group Boyce Avenue connect for a great cover of Justin Timberlake's "Mirrors." Normani's whistle at 3:31!

Where's that new Fifth Harmony music we need to be getting? The girls tweeted a picture of them meeting with L.A. Reid today, so hopefully its coming soon.
