Singer Katy Perry, who likes going over-the-top with her look sometimes, features sans make-up in her documentary Katy Perry: Part Of Me.
The 27-year-old spoke of her behind-the-scenes 3D film on The Ellen De Generes Show in the US.
The film is an access-all-areas look into the life of the pop star.
"When you see the film, it's a bit scary because there's a lot of shots of me bloated with zits and normal," thesun.co.uk quoted Perry as saying.
The Teenage dream singer admits she wanted to show a real account of her life on stage - and even her private life.
The film will also feature a tasteful mention of her divorce to estranged husband Russell Brand and their short marriage.
