Album of the year winner Beck may have been "excited" that Kanye West briefly stormed the stage at Sunday’s Grammys, but Shirley Manson is ranting mad.

The Garbage singer, 48, took to Facebook to blast West, 37, for the stunt, which was reminiscent of the time he famously interrupted Taylor Swift at the 2009 MTV VMAs to claim Beyoncé should have won the best female video Moonman.

Though everyone from West’s wife Kim Kardashian to buddy Jay Z, award presenter Prince and even Beyoncé herself visibly laughed when West “pulled a Kanye” on Sunday, Manson was not amused.

After West made comments on a Grammys aftershow that “Beck needs to respect artistry” by handing over his the statuette, Manson shot back, “Dear Kanye West, It is YOU who is so busy disrespecting artistry.”

She accused him of “rudely and savagely” attacking Beck, saying, “You make yourself look small and petty and spoilt … Grow up and stop throwing your toys around. You are making yourself look like a complete t—.”

She added, “Ps.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.”

Representatives for West have not returned PEOPLE’s request for comment.
