It’s official: Our girls just killed it again.

After utterly dominating the stage during the MTV EMAs livecast over the weekend, the professional BO$$es known as Fifth Harmony just hit Good Morning America to bring “Sledgehammer,” their latest Reflection banger, to life in the early AM. And truly, they nailed the performance!

From the copious hair flips to the tight choreography, the girls are delivering top notch girl group goodness — and the vocals were solid, too. The ladies looked like they were having a blast, and the crowd full of dedicated Harmonizers was eating it up as well. This could be the biggest moment yet for 5H.
