John Mayer claims Pink kneed him in the “nuts” after a meeting last year.

(Please excuse while we laugh our asses off.)

On Monday, the “Gravity” singer posted a cryptic message on his Twitter account, suggesting the “Funhouse” star attacked him following a heated encounter outside a luxury Hollywood hotel.

“Last year P!nk kneed me in the nuts outside Chateau Marmont. I was pissing blood for days. Did I make a scene? (sic),” the 31-year-old musician tweeted as part of a rant on the Perez Hilton – Will.i.am controversy sweeping the web.

Of course, it is possible. Pink has made no secret of her disdain for the notorious ladies man.

Last October, Pink branded John her “Most-Hated Celebrity” after they met at a party in the Hollywood Hills. “I got into an argument with him. I don’t believe him as much as he believes him. He said something along the lines of, ‘I only shag really stupid women,’” the star said afterward.

“And I said, ‘I guess they would have to be.’ I don’t get him at all.”
