She may be known for experimenting with different hair and make-up looks.
But Katy Perry has proved she is confident in her own skin, showing off her barefaced beauty as she appears in her upcoming 3D film documentary Part Of Me.

"I took my makeup off! Oh, everyone is screaming around the world, ‘The horror," she told Ellen DeGeneres last week.
''Look, I don't always want to look bloated with zits, but it's real, it's human, right? We're not always so pretty, and sometimes that can bring people together.''
Seeing the singer's blank canvas is quite a novelty, considering she is always spotted with a new daring look, often complete with bright coloured hair.
The film will be a realistic account of Katy's life which is said to document her brief marriage to Brit funnyman Russell Brand.
