Fifth Harmony transformed the Dancing With the Stars ballroom into a reggae club during Tuesday's finale episode with new single "All In My Head (Flex)." The all-female group had the stage crammed with backing dancers doing tight choreography.
The album version of "All In My Head" features rapper-singer Fetty Wap and is on the group's upcoming second LP, 7/27. On Sunday, the group performed the album's steamy first single, the Ty Dolla $ign-featured "Work From Home," at the 2016 Billboard Music Awards.
7/27, which follows 2015's Reflection, is named after the day the quintet were united on reality singing competition The X Factor. (Member Lauren Jauregui also told Rolling Stone that the titular reference to a 727 jet indicates their desire to "take off" with the LP's release.)
