Well this came out of nowhere!
Katy Perry has been added to the amazing lineup which already includes Adele, The Weeknd and Daft Punk, as well as Bruno Mars.
Katy Perry hasn’t performed at the Grammys since 2015 and hasn’t put out new music since “Rise” in the summer of 2016.
Could we be getting new music from her on Sunday?
Or will she release it before…
