Fifth Harmony will release their debut UK single Sledgehammer on 7th December 2014.
Ally Brooke, Normani Kordei, Lauren Jauregui, Camila Cabello, and Dinah Jane were put together on The X Factor US after auditioning as solo artists. They had Simon Cowell as their mentor and finished third on the series.
Now signed to Epic Records and Syco Entertainment, Fifth Harmony released their debut EP Better Together earlier in the year which stormed into the iTunes Top 10 in 41 countries.
Fifth Harmony will perform Sledgehammer on The X Factor semi-final later this year. The track was written by Meghan Trainor who is best-known for her chart-topping hit All About That Bass.
