Slay Harmony is really what they should be called from now on. The five-piece has been slaying for months now with each new release and each live performance, and their new electro-pop slayage, 'Sledgehammer', has finally gotten an equally gag-worthy video.

Fifth Harmony bring the sexy back in their 'Sledgehammer' video, dressed in white and breaking out some fierce choreography. The girls look stunningly beautiful (even if their outfits are a tad unflattering), and they know how to work that hairography.

They even give us a Britney Spears-inspired moment when they sit on swings and have a fan blowing their locks about. It's all stunningly gorgeous, and then one man brings in the much talked about sledgehammers and uses them to play the drums. It's a hard hat affair that leaves you breathless.

Fifth Harmony's debut album Reflection will be released on January 27th.
