Watch Fifth Harmony perform “All In My Head (Flex)” on The Voice Australia

The X Factor US girl group, Fifth Harmony, performed on The Voice Australia, during the Grand Finale and they totally knocked it out of the arena.

The girls performed their new song “All In My Head (Flex)” with killer vocals and a full dance choreography.

Fetty Wap features on the track, but did not join the girls on stage. Instead, the backing track provided his vocals while the girls danced.

Fifth Harmony out-performs themselves with every performance. Choreography completely on point and in sync, vocals are nailed to perfection, outfits are gorgeously sexy. How will these girls top this performance? They completely smashed it, yet again.

They performed in front of coaches Jessie J, Delta Goodrem, The Madden Brothers and Ronan Keating.

Jessie J and Delta Goodrem can be seen out of their chairs, during the video, singing and dancing along, whilst Ronan Keating has some movement in his seat. The Madden Brothers, consisting of Joel Madden and Benji Madden from the band Good Charlotte, stand up and groove along to the song as well.

Fans in the audience took to Twitter and Instagram to post photos and videos.

The Voice Australia Season Five Grand Finale took place on 10 July 2016, it was won by Alfie Arcuri, with Adam Ladell as runner up. Tash Lockhart and Ellen Reed came third and fourth respectively.

Fifth Harmony weren’t the only guests to perform on The Voice Australia that night. The Madden Brothers got out of their coach seats and performed with their band Good Charlotte. They sung “Life Can’t Get Much Better” during the Grand Finale.
