Chart-topper Katy is currently on a press-run in Australia and stopped by morning show Sunrise yesterday (4 March) to spill the beans on kissing her good friend Miley, as well as discussing her upcoming tour and new music.
Explaining how her special moment with 21-year-old Miley came about, Katy said: "I went to her show, which was amazing, and she has this one part where it's like a kiss-cam and I just walked up to her to give her like a friendly girly kiss, you know, as girls do, and then she like tried to move her head and go deeper and I pulled away.
"God knows where that tongue has been, we don't know! That tongue is so infamous!"
Last month, outrageous songstress Miley was caught locking lips with Katy during her 'Bangerz' tour show in Los Angeles - the same concert that saw her eating a pair of pants on stage and twerking on top of a car!
And now Katy is preparing for her own tour, we can only imagine whether Miley will make sure to be in the crowd for round two!
But that is far from 29-year-old Katy's mind right now, as she is getting in the zone for her upcoming concerts and sticking to a strict diet so that she is in the best possible shape.
Talking about the run-up to her tour, she said: "It's a lot of work. I have to be very focused. Right now I have cut out all alcohol, all fatty foods, a lot of dairies [cut out]. I go home and I'm going to have mostly vegetarian [food] with some protein on the side.
"I'm almost 30 guys, my body does not snap back anymore! I can't just go around eating McDonald's like I used to."
With over 51 million Twitter followers and numerous smash hits under her belt, Katy is one of the biggest female singers in the world.
However, when this was suggested to her on Sunrise yesterday, she instantly dismissed the claim and insisted that bootylicious Beyoncé was a more successful star.
"Beyoncé is the biggest female entertainer in the world," she said. "Mariah Carey is fabulous for a throwback... I sang all of her songs growing up."
