The 22-year-old Little Mix singer, along with her band mates Jade Thirlwall, Leigh-Anne Pinnock, and Jesy Nelson, joined Jason on stage during his Everything is 4 tour for a performance of “Secret Love Song”.
“Thanks so much @jasonderulo for having us at your show @TheO2 to sing #SecretLoveSong,” Little Mix wrote later on Twitter.
