Katy Perry has said she physically 'convulsed' when she heard that Russell Brand had filed for divorce 14 months into the marriage.
The Teenage Dream singer said she was preparing to take to the stage and perform when she heard her husband had filed to end their marriage last December.
Katy Perry bares all about her split from Russell Brand in her new movie Katy Perry: Part of Me which contains footage from her world tour.
She said: "I was convulsing a little bit ... I still have to find the balance, I had to separate my personal from my professional."
The popstar admits she had to "separate" herself from the problem because she was a "professional", she still struggled to deal with the turmoil in her personal life.
As an entertainer, I knew what my job was and I shouldn't like take it out on my audience, they've always been there for me."
Footage of the split news is shown in her new movie Katy Perry: Part of Me, and she admits looking back at her life for the film has been a strange experience as she realised she has achieved everything she wanted out of life at the age of 27.
Speaking on the Kylie and Jackie O Show on Australian radio station 2Day FM, she said: "You see so much footage of me as a young kid, as 18, speaking to the camera telling the camera, this is what I want to do, this is where I want to go, this is what I want to achieve in life, it's very surreal to be looking back at that and going ... 'Oh, well I've done it.' "
