The X Factor winners went straight to the top with their first proper single since their cover of Damien Rice’s ‘Cannonball’ last Christmas.
The girl group sold over 107,000 copies over the past week, and knocked last week’s chart-toppers Sam and the Womp down to second place with ‘Bom Bom’.
“Wooh! Number 1! We want to thank all the Little Mixers who went out and bought the single,” the band said. “You’ve made all our dreams come true.”
“It means a lot because obviously we got a number one at Christmas with ‘Cannonball’, but that wasn’t our song really, so now that we’ve become number one with our own song that we wrote, we’re so proud, best feeling ever. Continue to listen to it and dance away in your bedrooms in your pants!”
