The INSIDER Summary:

Katy Perry revealed that her song "The One That Got Away" was written about fellow singer Josh Groban.

She told this bombshell to host James Corden during a weekend-long live stream to promote her new album.

Groban and Perry were rumored to be dating in 2009 and she even got a fake tattoo of his name — although it was misspelled.



Katy Perry has been romantically linked to many a famous face — John Mayer, Orlando Bloom, Russel Brand, to name a few — and people love to speculate about which of these dark-haired, attractive dudes her songs could be written about.

But when revealing who the subject of her song "The One That Got Away" was, Perry name-dropped another famous, attractive, dark-haired man — and it was not who anyone was expecting.

She told host James Corden that the song is actually about singer and Broadway star Josh Groban.

It all went down during Perry's weekend-long livestream to promote her album called "Witness World Wide," in which she secluded herself in a house and filmed her for a whole weekend. Corden stopped by on Sunday to play a game of "Spill Your Guts or Fill Your Guts," where Perry would have to answer a personal question or eat something horrid.

Corden asked her to rank her exes — Orlando Bloom, John Mayer, and Diplo — on how good they were in bed. Perry surprised everyone — well, me at least — when she suggested that Groban be thrown into the mix.

"Josh Groban is in there," she said, before adding, "I'm just kidding. He's amazing."

She then clarified that he should not be thrown in to be ranked, but revealed that she wrote the famous song about him.

"No, he's not in there. But I do want to say, people are like, who is 'The One That Got Away' about? That's Groban," she said, making a head-exploding motion, which, yes, describes how I felt about it. "He's one of my good friends."

In dissecting the lyrics, it does make some sense. They are both from in and around Los Angeles, so they could have met "summer after high school." Jury is still out if they had — or have — matching tattoos, but Perry did rock a fake and misspelled "Josh Grobin" tattoo in 2009.

They were rumored to have dated in the past but Groban denied it, saying they are "good friends" who "skated the line" on dating.

Groban has yet to respond to this latest revelation as he was busy having his own big night at the TONY Awards Sunday evening, but as someone who listened to "You Raise Me Up" about a million times in high school, I have to say, I feel you on the crush, Katy.
