In an appearance on Good Morning America on Tuesday, Katy Perry [photos] compared her divorce from Russell Brand to a scar.
"It's like a scar," said Perry. "Sometimes you look on your legs or your arms and you see this scar."
"And sometimes they're bad and it reminds you of the thing that you learned or what not to do again. But you needed that reminder. And these are valuable things. They're life lessons that help me in the future."
The 27-year-old singer is making the rounds to promote her film 'Part of Me', which shows her deeply religious parents' objection with her wardrobe, among other things.
"Katy, I'm not going to watch you if you have half your clothes off," says her mother in a previewed scene.
The feature even details Perry's close relationship with her sister, Angela.
"I told her I was going to be this one day," she says. "And I said I was going to take her along with me. And I've taken her along with me. And she's kind of like my warden."
"She's the one that has that invisible leash you see mothers and the children in the malls, they're tied to and they kind of yank when the kid gets out of line? That's my sister."
As for any unflattering scenes in the film, Perry says she left them in to show fans the "real side."
"I'm okay with showing that real side and stripping that down. I even like the scenes where I left in the movie that maybe weren't under the most flattering lights and I looked obviously exhausted and tired."
"I just wanted to kind of show that like really at the end of it all I was just a normal girl, pretty plane Jane, who had an idea, planted a seed and watered it."
