Pink has hit back at the Recording Academy President Neil Portnow following his comments that women in music need to "step up" if they want to win at the Grammy Awards.
Portnow made his comments following the criticism that male winners dominated the ceremony held at Madison Square Garden in new York City on Sunday night.
He was quoted as saying after the ceremony: "It has to begin with ... women who have the creativity in their hearts and souls, who want to be musicians, who want to be engineers, producers, and want to be part of the industry on the executive level. [They need] to step up because I think they would be welcome."
Pink, 38, was furious with Portnow for his alleged slight against all the female recording artists and women working in the music business and posted a handwritten letter on Twitter in response.
The letter read:
Only one woman, Alessia Cara, who was named Best New Artist, won a major award at the Grammys.
Pink - whose real name is Alecia Moore - performed 'Wild Hearts Can't Be Broken' at the ceremony but lost out on the Best Pop Solo Performance to Ed Sheeran, the only male artist nominated in the category.
Bruno Mars was the big winner at the 60th Annual Grammy Awards, picking up six prizes including Album of the Year and Record of the Year for '24k Magic', and Song of the Year for 'That's What I Like', as well as Best R&B Album, and Best R&B Performance and Best R&B Single for 'That's What I Like'.
In addition, his LP was also recognised as Best Engineered Album, Non-Classical.
