What happens when you have a full-on choir and Little Mix in the same room?

A good old sing along, duh!

The choir and Little Mix were fresh from pranking Roman Kemp at the request of Marvin Humes! Leigh-Anne stormed out of the interview after being asked about her ex-boyfriend. 

After what felt like an hour of awkward filling, she ran back in with the choir to reveal it had all been a stitch up! 

Off the back of the ladies' world exclusive performance on The X Factor they caught up with Capital's Dave Berry, George and Lilah to reveal exactly who their latest single is about. 

"Shout Out To My Ex" is being described by the band as a 'happy break-up song.'
