WATCH: Fifth Harmony's 'All in My Head (Flex)' Music Video

Recently they've been storming the charts with hits like 'Worth It' and 'Work From Home'. All about female empowerment...ahem.
Thanks to 'All in My Head (Flex)' we now know exactly what the girls meant by working from home. Featuring Fetty Wap on the track, this reggae-inspired jam features a saucy video just to match. Looks like that transition from tween stars to sultry songstresses is compete.

The girl groups second studio album 7/27 is out now.
