Little Mix celebrate getting number 1 UK single backstage at Echo Arena on July 18, 2015 in Liverpool, England.

The ladies of Little Mix recently stopped by BBC Radio 1's Live Lounge to discuss their upcoming third album and perform a captivating cover of Jason Derulo's Top 10 smash "Want To Want Me"… with a full choir and organist, no less! Check it out below:

After teasing a stripped-down balladic take on the dance hit, the U.K. girl group speeds up the tempo and leads a chorus of handclaps through the first chorus. The video is a little long, but you'll want to stick around for that epic key change and… wait, is that a transition into Natalie La Rose's Top 10 hit "Somebody"?!

Earlier this month, Little Mix announced that its third studio set, Get Weird, will be released worldwide on Nov. 6. Lead single "Black Magic" has already hit No. 1 on the U.K. singles chart.
