Reports originally began to swirl when Miley and Ariana secretly liked tweets discussing the exciting new project.
One big clue that pretty much confirmed that the reports were true is when the official Charlie's Angels reboot GIPHY account uploaded and then deleted a post tagging all three girls!
Adding fuel to the fire was when mysterious new Instagram stickers (which have now also been deleted) for the upcoming film which stars Aladdin's Naomi Scott, Ella Balinska and Kristen Stewart appeared when searching all three artists in the dropdown menu when adding a new Instagram story.
It's not the first time Miley and Ariana have collaborated as the pair released a dreamy cover together for Miley's 'Backyard Sessions'.
Relive that iconic moment below.
We can't imagine what the pair will sound like with Lana but we are honestly so here for it.
