Katy Perry: Divorce from Russell Brand was a lesson well learned and now I have a second chance
In her new 'rockumentary' Part Of Me, which premiered in Sydney on Saturday, Katy, 27, is shown struggling to make her relationship work during her California Dreams tour.
'I'm trying to keep my marriage alive. He should be [coming to see me] but he's not,' Katy complains in the film.
Katy's friend chips in: 'She should be resting. But she wants to fly to wherever Russell is to show she cares. She's running herself ragged.'
After finding out Russell has filed for divorce in December, Katy cries and admits, 'I'm a romantic, and I believe in the whole fairy tale. Love is the dream but the reality is making it work. I did everything I could - but it still failed.'
But Katy picks herself up and is determined to stay optimistic.
The singer ends the emotional film by revealing she's feeling positive about the future.
'I feel like I have a second chance at a brilliant life,' she tells Australian TV show Sunday Night.
'There's nothing I regret because you can't buy a lesson and they're so valuable.'
Katy's documentary Part Of Me is released on 5 July.
