The former Girls Aloud beauty has enlisted the help bandmate and close friend Nicola Roberts to craft her new single, apparently named That’s My Song.
It will be her first song since her last release in 2014, Only Human.
According to The Sun, Cheryl has registered the new song online, listing Nicola as one the authors alongside Iain James.
He starred alongside Kimberley Walsh’s husband Justin Scott in band Triple 8.
A source close to Cheryl told The Sun Online: "Cheryl is back in the studio and music is her main priority for 2018."
The former Girls Aloud beauty has kept away from the music scene after welcoming her first baby Bear with boyfriend Liam Payne, who has since released singles away from his boyband One Direction.
Nicola had previously opened up on writing music for Cheryl, telling The Sun: "I’m writing for Cheryl and also for myself. Hopefully those songs are good enough to make it out into the world."
Cheryl previously hinted she was working on new music weeks ago, when a fan asked her online: "What about your music?" – and the Newcastle native gave a positive response.
The X Factor judge wrote back: "Working on it sis", along with a kissing face emoji.
Despite her boyfriend, Liam Payne, hinting earlier this year that her career was behind her, Cheryl has previously hinted that she is indeed planning on making some fresh tunes.
