Katy Perry is a pop princess in plaid for Elle UK's September issue.
The sexy songstress -- who just revealed her next album, PRISM, will be released October 22nd -- is gracing the fashion mag's upcoming cover in a sophisticated punk look from Dolce & Gabbana.
Katy opened up to Elle UK about the men in her life, including her relationship with John Mayer and her close friendship with Robert Pattinson. She even revealed how she made it clear to Rob's ex, Kristen Stewart that she and the Twilight stud were just friends.
"I sent her a text message saying: 'I know you’ve seen all this stuff but you know I would never disrespect you. I’m not that person. I’m just trying to be a friend to him but it is unfortunate that I do have a set of t*ts,'" Katy explained to the mag.
As for her on-again, off-again romance with notorious ladies man John Mayer? Katy said: "He pulled away. That was a big hello for me. I realized I could lose the person I loved and I had to deal with some things, issues I think a lot of women have. You can be strong in one aspect of your life but submissive in another. ... [But] I'm not interested in taming anyone - I'm pretty wild myself."
Perry confessed that she was "madly in love" with Mayer in Vogue's July cover story. The pair were spotted on a dinner date as recently as last Tuesday and they also showed off some patriotic PDA on the Fourth of July .
