Leigh-Anne Pinnock, Jade Thirlwall, and Perrie Edwards are releasing new music "very soon" after Jesy Nelson left the group in December.
Leigh-Anne told The Sun newspaper's Bizarre column: "We have new music coming very soon. We're working on something really exciting that will be out this spring, and can't wait for you all to hear it."
The girl group recently celebrated their first number one as a trio with Sweet Melody topping the UK Singles Chart.
Jade said: "It's also special because it's our first number one as a trio. Starting off 2021 with a number one is amazing."
