Shirley Manson, lead singer of alternative rock band Garbage, slammed Kanye West for ridiculing Beck for winning the Grammy for album of the year on Sunday. The artist hit back at Kanye, who interrupted Beck’s speech by running onto the stage to defend his friend Beyoncé, who was a nominee in the same category.

Here is the post on Manson’s Facebook page:

Dear Kanye West

It is YOU who is so busy disrespecting artistry.

You disrespect your own remarkable talents and more importantly you disrespect the talent, hard work and tenacity of all artists when you go so rudely and savagely after such an accomplished and humble artist like BECK.

You make yourself look small and petty and spoilt.

In attempting to reduce the importance of one great talent over another, you make a mockery of all musicians and music from every genre, including your own.

Grow up and stop throwing your toys around. You are making yourself look like a complete t---.

P.S. -- I am pretty certain Beyoncé doesn't need you fighting any battles on her account. Seems like she's got everything covered perfectly well on her own.

On Monday, Kanye, who arrived in New York City with wife Kim and daughter North West, defended his actions by saying that he was not disrespecting Beck when he jumped on the stage, TMZ reported.

Kanye looked like he was going to say something but later turned back and jumped off the stage. The attempt was initially seen as a joke, but that perception changed when he later commented after the show: "I just know that the Grammys, if they want real artists, to keep coming back, they need to stop playing with us. We ain't gonna play with them no more.... And Beck needs to respect artistry, and he should've given his award to Beyoncé."

Despite his comments, Beck said that he thought Kanye was a “genius” and “I aspire to do what he does.”

In 2009, Kanye stole the microphone from Taylor Swift during the MTV Music Awards and said, “Yo, Taylor. I'm really happy for you. I'ma let you finish, but Beyonce had one of the best videos of all time.”
