On Wednesday, the 31-year-old British singer dropped a major tease for the mystery feature with a peek at the album cover.

"Guess ?" Charli captioned the photo.

The snap featured what appears to be Charli on the left bearing a white lacy lingerie set and "lower back tattoo" inked on her – you guessed it – lower back, in a nod to the chorus of Guess.

On the right-hand side, the mystery collaborator is seen in an oversized tee and baggy pants over several pairs of boxers.

While the sense of style is clearly reminiscent of Billie's, it was the secret figure's rings that had fans the most confident that it was indeed her.

Eagle-eyed stans pointed to a recent IG photo from Billie, which saw her donning the same rings from the album cover.

Guess will mark the fourth remix of Charli's Brat era and follows up the fan-favorite Girl, so confusing revamp that famously saw her and Lorde "work it out on the remix."

The Boom Clap artist didn't spill when the next remix will hit the airwaves, so Billie fans will have to stay in suspense for at least a little longer!
