In a carpool karaoke episode with James Corden, P!NK explains who the first person to break her heart was in this funny clip (Skip to 2:50 - 4:15)
Apparently after meeting Jon Bon Jovi as a young singer, she told him about her childhood love for him. He then sent her a bouquet of flowers years later with a pair of leather trousers attached.
He also congratulated her on her People magazine cover! 💕
