If you've been hoping for and dreaming of a collab between the Vamps and Fifth Harmony while they're on tour together, then you're finally in luck! The Vamps took advantage of sharing the road with their pals Fifth Harmony by inviting the quintet on stage to help the boy band perform their latest single 'Somebody to You.'

Normani, Lauren, Camila, Dinah-Jane and Ally joined the British boys during their set in Manchester, N.H., to lend their vocals on the cheery love song. The Vamps had already started performing when the girls were brought out to sing the parts led by Demi Lovato in the studio version.

5H held their own during the 'Neon Lights' singer's verses, jumping around on stage with Brad, James and Connor. (Tristan rocked out behind his drum kit, of course.) As much as we love Demi singing with the Vamps, the live version with the 'X Factor' girl band is also totally killer!

Check out the Vamps and Fifth Harmony sing 'Somebody to You' in the video above!
