Little Mix performed live in Leicester Square's M&M's store yesterday, to help launch the Limited Edition Union Jack pack of red, white and blue peanut M&M's. Yummy.
No prizes for guessing which song they performed - Perrie's trademark En Vogue arm move really gives it away.
Unless she's just so smug about her and Zayn Malik's relationship that she's randomly fist pumping the air. We probs would be.
