Check out Fifth Harmony performing new tune, "Reflection," while opening for Austin Mahone's tour in his hometown of San Antonio, TX, on Friday. The song isn't officially out yet, but a fan captured the new track on video, so we're happy to give you a sneak peek!

Can you hear the crowd go crazy with screaming when the girls ask if they are ready for new music? I think we're all ready for it.

Dressed in summery white, the VMA nominees delivered the sultry R&B number, complete with slinky choreo. Sharing the sentiment of Carly Simon's classic "Your So Vain," the gals sing about a guy who's confusing his game for the catch he has in front of him: "Boy, I ain't talking about you/I'm talking to my own reflection." Tell it like a "Bo$$" ladies!

The song presumably hails from Fifth Harmony's forthcoming debut studio LP. 5H will be touring with Austin through September 9.
