Perry released a new video for the single and title track, "Smile." The talented performer transforms herself into a clown and plays a circus-themed video game in the video.
Perry sings, "I'm thankful, Scratch that, baby, I'm grateful! Gotta say it's really been a while. But now I got back that smile."
It ends with Katy smashing the pie in her face!
This is Perry's fifth studio album. It is set to hit shelves and digital retailers on August 28.
