Mabel's record label have teased news of her upcoming single, saying it could be "as big, if not bigger" than her 2019 smash Don't Call Me Up.
Polydor co-president Tom March told Music Week that after breaking through last year, 2020 will be the year they "cement Mabel as a global pop star".
Mabel scored a run of hit singles across 2018 and 2019, including Fine Line and Mad Love, but it was Number 3 hit Don't Call Me Up that proved her strongest track, finishing in the Top 10 biggest songs of the year with 1.08 million chart sales. It's also nominated for Song of the Year at this year's BRITs.
Mabel's new single, which doesn't yet have a title or release date, is written with Kamille Purcell and Steve Mac, who worked on Don't Call Me Up.
"We’re coming out strong, we’ve got big single coming that we're really excited about," March said.
"It feels as big if not bigger,” he said of the new track. "It's another record with Steve and Kamille and it sounds like another huge global pop hit to me. So we start the year strong, the same as we did last year.
“Mabel is making a style of pop music that sets itself apart, there's a difference to other successful British and international pop stars,” said March. “It’s the same with her sound and her imagery.”
As well as Song of the Year, Mabel is also nominated for Female Solo Artist and New Artist at this year's BRITs, which take place on February 18.
