When Leigh-Anne Pinnock has had enough of her boyfriend, she calls the other three girls, asking them to help "get him out my hair." Jade Thirlwall, Perrie Edwards and Jesy Nelson show up at her doorstep in their pajamas. The four mix drinks, demolish five pizzas and use their hair straighteners as pretend microphones. They even take a page straight out of Cocktail, sliding across a wooden-floored foyer in their socks and undies to sing their parts.
