Perry, who reportedly split from longtime boyfriend John Mayer, was in Australia to announce the Aussie leg of her Prismatic tour and give some weather reports, and while doing a radio interview, was asked if she noticed that Miley was about to take the kiss to the next level, adding a little bit of that oh-so-famous tongue.
"Yes, I saw that and that's when I walked away," Perry said. "I was like that tongue is infamous I don't know where it's been. You slide down it every night. I was just going in for a 'hey, girlfriend' kiss."
Perry was referring to the moment at the beginning of Cyrus' show when she slides down a giant tongue. However, there were no hard feelings after the lip-lock, which took place at the Los Angeles stop of Miley's tour, with Perry tweeting a photo of the two of them after the kiss.
That wasn't the only exciting thing that Perry has accomplished as of late. The "Dark Horse" singer had a "miracle" recently, helping her sister deliver her baby in her living room.
"My sister gave birth in her living room and I got to be an assistant doula, which is a home birth. It's kind of just there for support," Perry said. "I was like Scorsese filming everything, getting in there. She doesn't want to see that for about a year though. I was in it, I probably shouldn't give too many details. My sister is actually the true rock star, she gave birth in her living room, without a single Advil."
So did watching the birth make Katy want to have some babies of her own anytime soon?
"I don't know if I could do it her way, because that was super intense. But my baby will be super intense because it's basically in the form of a tour for a year and a half."
Katy kicks off her Prismatic world tour in May.
