Girl group Fifth Harmony will be taking the stage on 'Dancing With The Stars' later this evening (May 19) for the show's finale episode. 

The beauties are set to perform on the programme tonight and other confirmed acts include 'Elastic Heart' songstress Sia, Jason Derulo, Patti LaBelle, Andy Grammer and former LMFAO hitmaker and 'Dancing With The Stars' contestant, RedFoo. 

5H, meanwhile, were at the Billboard Music Awards over the weekend and revealed that they were offered the chance to perform at the ceremony, but had to turn down the amazing opportunity: "Because of the success of 'Worth It', we were given the opportunity to do an acapella version of the song during the show. Because we didn’t get to do a rehearsal in the arena until the day of the show, and with the nature of the production of this song, we didn’t feel happy with how it sounded.

"You know we strive for perfection so after a conversation with our team, we all decided it was best to wait for a moment to showcase Worth It at its best. It was a united decision that we all made together. We love you and your passion and hope you can understand that part of our journey is making the right decisions in tough moments."
