Washington, June 23 Musician John Mayer has claimed that singer Pink had kneed him in the genitals outside a luxury Hollywood hotel last year.

The 'Gravity' singer posted a cryptic message on his Twitter account, claiming that Pink attacked him outside a luxury Hollywood hotel.

"Last year P!nk kneed me in the nuts outside Chateau Marmont. I was p***ing blood for days. Did I make a scene? (sic)" Contactmusic quoted Mayer as saying.

Pink had called Mayer her "most-hated celebrity" after they met at a party in the Hollywood Hills last year in October.

She said: "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 sh*g really stupid women.'

"And I said, 'I guess they would have to be.' I don't get him at all," she added. (ANI)
