Just days after Perry officially announced the title of her fourth album last month, the cover artwork for Witness dropped online Thursday, May 18.

Featuring a somewhat spooky '80s new-wave motif, the album cover, which first appeared on Amazon, finds Perry posing with her hands over her eyes, her red lips parted as an eyeball peeks through her mouth. (Shut up and put your eyeball where your mouth is?)
