Rocking a platinum pouf, an animal print jacket and yellow leggings, Katy Perry plopped herself onto Jimmy Kimmel's couch on Monday night (March 5) and sighed, "there's a reason the word 'pain' is in champagne." You see, she had, literally, just come from shutting down Madonna manager Guy Oseary's Oscar party and performing at a charity event in support of the Children's Hospital Los Angeles alongside Jamie Foxx. She was exhausted, but not too pooped to talk about next week's launch of the re-booted American Idol and play "do you remember this friend" with an old pal from school.

Perry kicked things off by praising Kimmel for striking "such an incredible, beautiful balance" during his gig hosting Sunday night's (March 4) Academy Awards, which she said felt very inclusive and hit just the right note. She also revealed that while new Idol judge Luke Bryan is like her brother, third wheel Lionel Richie is more like their goofy uncle who they love to torture. "We're ruining his legacy," she promised.

She also gave prospective Idol singers a bit of advice: don't sing her songs. "We don't need our bum-bums kissed," she said of herself and fellow judges, who just want to see the budding stars' talent, not have their egos stroked yet again. "New stars are born every day," Perry said, assuring Kimmel that there is plenty of talent left in the Idol sea.

Katy also played a game called "Blast from the Past," in which Perry had to figure out which of the six people on FaceTime were old friends of hers and which ones were total strangers. She actually nailed it on the second shot, picking out her sixth grade pal "Erica" (actually Ahnika) from Santa Barbara Christian School, who went on to tell a couple of delightful boob-related stories from their childhood.

Perry went on to talk about her wild Oscars night, and explain to Kimmel what the term "wig" means. Watch below, and check out the premiere of American Idol on Sunday, March 11 on ABC.
