Katy Perry, honestly, does everything. She’s the face of Covergirl, does voiceover work on the Smurfs movie, has a few makeup lines, and SHE SINGS. WOW.

Who cares what she's singing, it's a hit:
You can literally just make up your own words and it'll sound perfect.
Just like when Miley finally released Malibu:
Wow or when Gaga performed The Cure for the first time at Coachella:
Or just everyone @ Taylor Swift's music, in general:
Even the Katy stans (that don't know words to her own songs) know what's up:
It's basically everyone at their fave's concert TBH:
