Pink almost vomited when she learned Jon Bon Jovi had married Dorothea Hurley in 1989.
The 38-year-old singer had a crush on the 'Livin' on a Prayer' hitmaker as a little girl and even had ambitions to marry him one day - so she was "devastated" when she heard that the New Jersey rocker had instead tied the knot with his high-school girlfriend.
Recalling her heartbreak during the latest episode of 'Carpool Karaoke', Pink told James Corden: "[I was] probably seven or eight.
"I still remember I was in the car coming home from singing lessons and they said on the radio that he married his high school sweetheart Dorothea, and I almost threw up in my mouth.
"I ripped his posters off the wall, threw them out, and didn't come out of my room for days. I was devastated. It was the first time someone ever broke my heart."
More than a decade later, Pink came face-to-face with her childhood crush and told him about her heartbreak.
The 'What About Us' hitmaker - who has been married to Carey Hart since 2006 - shared: "I told him the first time I met him.
"We did a radio show in New Jersey and I think I was like, 22, and I was like, 'How are you guys? Are you happy, you and Dorothea?'"
In response to Pink's confession, Bon Jovi sent the singer - who has kids Willow, six, and Jameson, 10 months, with her spouse - a massive flower arrangement, which featured a pair of leather pants attached to the basket.
Pink explained the significance of the pants to James, telling the chat show host: "The flower basket was like, life-sized, and there was a pair of leather pants with a note that said 'Now you can finally get into my pants."
But Pink's husband didn't see the funny side of the gesture.
Recalling his reaction, Pink said: "Carey threw them out the window!
"It wasn't weird, it was a joke. Like, I thought it was really funny. But Carey didn't think it was that funny."
