Fifth Harmony Are Summer Goddesses in 'All In My Head (Flex)' Video feat. Fetty Wap

Fifth Harmony are continuing their pop summer takeover with their new video for "All In My Head (Flex)." The new single, which follows the uber-catchy "Work from Home," features Fetty Wap and embodies the sweltering season with its reggae influence.

The video, helmed by Director X, embraces that vibe with Ally, Dinah, Camila, Normani and Lauren strutting on the beach, proudly showing off their curvaceous bodies and letting their smiles glow as bright as their tans. Fetty Wap does make an appearance, and oddly chooses to wear a sweater. Maybe he's still working on his summer body?
