The 'Wide Awake' singer has previously admitted that she felt uneasy addressing her split from Brand in Katy Perry: Part of Me, but she has now told MTV News that her personal trauma could serve as an "example" for fans.
"It's not about the problem; it's about how you solve it. And if I can be an example showing people that they don't have to lay down and die because they've been thrown a curveball, then that's great," Perry said.
"If I can help someone else out because they feel like the only loner in the world or the only person that is going through the situation and they see me and they're inspired to keep moving forward, then I've done my job."
Katy Perry: Part of Me director Dan Cutforth echoed the star's sentiments earlier this week when he suggested that the divorce was a crucial element in the movie.
"There was never really any discussion of taking out the scenes that are a bit more emotional, maybe a bit more difficult, a bit harder to watch sometimes. I think it was important to Katy," Cutforth said.
Katy Perry: Part of Me is now playing in the US and the UK.
This week, Perry clarified that her relationship with Florence +The Machine guitarist Robert Ackroyd is not "serious".
