Katy Perry not ready to reveal all about Russell Brand

London: Singer Katy Perry says she has not cut the scenes of her split with British comedian Russell Brand from her upcoming 3D documentary- concert film ‘Katy Perry: Part of Me’, but has kept them limited.

She believes certain things should be kept between two people. "I didn`t get too detailed about the specifics because I believe that`s only supposed to be between the two people that are in it," thesun.co.uk quoted the 27-year-old as saying. "I just wanted to encourage people, to let them know that it`s okay if they have problems. It`s okay if they`re going through a situation, they don`t have to lay down and die, they can get through it," Perry said. The documentary releases July 5. IANS
