Little Mix had a surprise in store for fans at Capital FM’s Jingle Bell Ball on Saturday, Dec. 5: the first-ever live performance of “Secret Love Song” with Jason Derulo. The girls’ introduction of the song included an announcement that it will be their next single (in the U.K. and Ireland), a fact that was confirmed on Twitter soon after.

The group’s six-song set, taking place at London’s O2 Arena, kicked off with “Salute” and included “Move,” “Wings,” “Love Me Like You” and “Black Magic" in addition to "Secret Love Song," according to Capital FM.

"So we have an exclusive for you,” Little Mix reportedly said before launching into “Secret Love Song.” “We know you'll enjoy a cheeky little surprise. This song is going to be our next single. We hope you enjoy it.”

Jingle Bell Ball is a two-day event (Dec. 5-6) with a lineup that also features Coldplay, David Guetta and others on Saturday -- and Justin Bieber, Nick Jonas, Calvin Harris and more on Sunday.
