Katy Perry didn't hold anything back during her 72-hour Witness World Wide live stream on Sunday, June 11. Playing a game similar to "Truth or Dare" with James Corden, the 32-year-old pop star was asked by the funnyman to rank her last three lovers from worst to best based on their performances in bed.

The "Roar" hitmaker listed Diplo first, whom she dated for several months in 2014. Her most recent ex, Orlando Bloom, came in the second place. And John Mayer, whom she dated on and off for three years until late 2015, came at the top. She then quickly added, "They're all amazing lovers and I would have sex with all of them when I get out of this place!"

Katy made another shocking revelation when asked who is the "one who got away," saying that it's Josh Groban. "People are like, who's the one who got away? That's Groban," she said. "He's one of my good friends. I love him so much. He's the best."

Katy, meanwhile, asked James if he ever texted someone a photo of his penis. The "Late Late Show" host said he never had, joking that it is "underwhelming." He then joked about Orlando's nude photos during his and Katy's 2016 trip to Italy, "If I had Bloom's penis, I would never be clothed."

During the live stream, Katy also opened up about her suicidal thoughts and apologized to Taylor Swift.
