Kesha teases mystery artist collaboration with cryptic Instagram post.
While the fans in the comment section of her Instagram seems fixated on Taylor Swift being the mystery collaborator, there's plenty of other fun options to consider. Lady Gaga, Beyonce, Meghan Trainor. There's also no telling whether the mystery person is a vocalist, songwriter or producer...whoever it is, though, they have to be pretty famous already, otherwise keeping their identity secret would be pointless!
The most exciting part, though, is undoubtedly Kesha announcing she and her song partner are specifically crafting a "F*CK OFF" anthem.
