Katy Perry as seen in the movie New York - Arabstoday Singer Katy Perr went without makeup while filming her 3D concert film “Part of Me”. \"Well it\'s a lot of different parts of me, this film, and some of them are, well they were difficult to put in - especially the ones of me with no make-up,\" Perry said. \"Part of Me\" is set to release in July. Perry has promised that the project - which combines concert footage with her everyday life - will be interesting. The singer is likely to reveal some intimate details of her life. \"A lot of people have a lot of ideas about me, but this is a film that I made for myself, for my fans ... so that they can get the all-access pass. And I\'ve never been this revealing,\" she said. This is not the first time that we see Perry without make-up; her ex-husband Russel Brand posted a rather unflattering picture of Katy Perry on his Twitter page that shows the singer without a scrap of make-up.
