It has been confirmed that girl group Fifth Harmony will perform their brand new single 'Sledgehammer' on 'Good Morning America' in November. 

The girls will take the stage at GMA on November 6 to treat fans to a live rendition of the track, which was written by 'All About That Bass' hitmaker Meghan Trainor', and it was announced in a press release from Epic Records. 

Trainor took to her official Instagram page earlier today (October 30) and told her own followers that she's very proud of the song and how well it's doing commercially: "Such an honour to have @fifthharmony cut a song I wrote called #sledgehammer with @seandouglas and@jebergjonas ! Can't believe it's up at number 4 already sitting next to #allaboutthatbass."

The girls, meanwhile, are gearing up to release their highly anticipated debut studio album 'Reflection' on December 16 and MTV recently teased that a big event is being planned to celebrate the event: "We're still developing the creative and details around that, but we're looking to do something really big, really loud and definitely live."
