Katy Perry has been talking about all the footage of her with no makeup on and crying that's in her new movie Part Of Me 3D.
She said that being honest was important to her, however difficult it was to approve being in the movie.
Katy told Parade magazine:
There are a lot of things that are personally uncomfortable to show, especially me without makeup and completely bloated or crying.
"But Ive realised that its time for me to show my audience that you dont have to be perfect to achieve your dreams.
"Because nobody relates to being perfect Im okay with having bad dance moves. Im okay with having horrible lower teeth.
"Thats what makes me me, and for some reason its worked out all right.
We think she's lovely! Do you like it when stars show that they're not always perfect?
