When asked by James Corden to rank former lovers John Mayer, Orlando Bloom and Diplo from best to worst in bed, Perry ranked the music producer last in a game of "Spill Your Guts or Fill Your Guts" during the singer's four-day live stream.
"I don't even remember having sex... I won the Bronze metal in sex Olympics," tweeted Diplo who dated Perry for a few months back in 2014.
Ouch! But in Katy's defense she was visibly uncomfortable answering, so Corden prodded the singer along.
"Do you want me to help you?" Corden said to Perry. "I think Diplo's third, I do, because I think there's a reason people become DJs."
Perry reluctantly agreed that Diplo came in third place, then nodded her head "yes" when Corden suggested "then Bloom, then Mayer?"
"They're all amazing lovers and I want to have sex with all of them after I get out of this place." Katy said before confessing that Josh Groban would most likely be in her top three.
"People are like 'Who's 'The One That Got Away' about?' and that's Groban," she added.
