Katy looks sooo different without all her red carpet makeup on!

You might even pass her in the street without giving her a second glance. She looks totally different from the performer that belts out her best hits on stage in crazy costumes.

The shot is from her upcoming documentary movie, which gives fans a look at the whole backstage process – including her makeup routine!

Are you going to go see Katy’s movie?
