Katy Perry told British talk show host Graham Norton she got through her separation from ex-husband Russell Brand by focusing on her music and live performances for her fans.

As reported by The Huffington Post, Perry said, "I love being on stage and even though I went through some pretty tough times last year, I had to separate that because I know my problems are my problems and they are not the audience's problems. They are here to see a show and to be entertained, so I got on that lift, put a smile on my face and went up (on stage) with my t--s spinning!"

Perry's marriage to Brand lasted less than two years, and her performance of 'Part Of Me' at the Grammys seemed to be directed at him, even though she says the song was written well before the couple split.

Video clip of Perry chatting about Brand on the show hasn't surfaced online yet, but one clip has been released showing Perry and Cheryl Cole discussing singing competition shows and Simon Cowell in particular. Perry said she would consider being a judge on a program like that someday, but not right now. "I'm busy!" she declared. "I'm very flattered, but there's a lot of those types of shows, so you have to be careful with the one that you associate yourself with."

The show is scheduled to air on BBC America next weekend, June 16. The film 'Katy Perry: Part of Me' arrives on July 5.
