(Yahoo!) - Following her friend Kristen Stewart's split from Robert Pattinson, Katy Perry was photographed (on several occasions) lookin' kinda cozy with the former "Twilight" leading man. But it wasn't what it looked like, according to the pop star.

After reports surfaced that Kristen felt "betrayed" over Katy's apparent closeness to Rob, the singer reached out directly to clear the air ... by text message, of course. (Hey, at least it wasn't Twitter.)

"I sent [Kristen] 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," Perry revealed to Elle UK. "I'm just trying to be a friend to him but it is unfortunate that I do have a set of t**s.'"

Perry's friendship with the ill-fated "Twilight" stars has long been documented. In fact, one of the pair's final outings as a couple was to attend a birthday party for Perry's personal assistant.

Still, it's not like the raven-haired beauty hasn't had her own share of rocky romantic waters. After a failed marriage to Russell Brand, she hooked up with notorious ladies' man John Mayer ... and then they broke up ... and then they got back together ... twice. She blames their brief split on her own "issues."

"He pulled away. That was a big hello for me," she recalled. "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."

What kind of "issues," is she referring to, exactly? Apparently, Katy was finding herself attracted to "challenging" men. Though she quickly added, "I'm not interested in taming anyone — I'm pretty wild myself."

Wild or not, Katy conveniently left out any mention of whether Kristen ever responded to her note, which means we'll just have to wait and see if these two former BFFs put this bump in the road behind them. In the meantime, though, we're taking on bets on Katy's current beau and whether this time it will stick.
