The Price Tag star, who will be at the Summertime Ball in June, is clearly a big fan of Katy's cleavage after seeing her on stage in Sydney.
In a message on Twitter, Jessie J said: "Just met @katyperry. The show was incredible, she is beautiful and so sweet. I wish I had her boobs lol #greatnight."
Perry replied, "Nice to meet you too, you're a DOLL," she wrote on Twitter. "And p.s. the offer still stands... I'll trade my tits for your gams!"
Both stars are currently on separate tours of Australia.
