Perry declared her newfound infatuation via Twitter, following Pink's gig in Australia on Thursday. She wrote: "Out to see the P!NK show in Melbourne! She rules AUS! Can't wait, I KNOW she won't sing that song,"There U Go" but I chuckle and wish! (sic)"
She continued: "Okay, THAT was AMAZING! YOU MUST see the show when it comes to the STATES! P!NK @ her prime... so happy I went, inspired. Good morning USA!
"She's really great... Shows so many different dimensions and is still personable, relatable, f***ing RIPPED and wears HIGH A** HEELS. HOW? FAN!"
Last week, Perry also confessed to being a huge Gwen Stefani fan.
