Before and during the weekend, Katy Perry was broadcasting her life on a YouTube live stream aimed at promoting her Witness album.
She was very candid with her fans during this experience sharing many personal details, including her sex life.
James Corden was a special guest on her live-stream video, and they played a truth or date type game together. At one point Corden asks Perry to rank three ex-lovers according to their sex performances, from worst to best!
Perry listed Diplo first, then Orlando Bloom and then John Mayer, after saying, "They're all amazing lovers and I would have sex with all of them when I get out of this place!"
She also revealed that Josh Groban is the "one who got away."
"People are like, who's the one who got away? That's Groban," Perry told Corden. "He's one of my good friends. I love him so much. He's the best."
