Slipknot are rumored to have enlisted ex-Against Me! drummer Jay Weinberg -- a move Laura Jane Grace said the band will regret.

The outspoken transgender frontwoman of Against Me! took to Twitter to slam Weinberg (the son of Bruce Springsteen drummer and Conan O'Brien bandleader Max Weinberg) who reportedly never told Grace or the other members of Against Me! that he was quitting in 2012 after two years with the band.

Here's what Grace said:

While there's been no official word from Weinberg or Slipknot, a new promo video for Slipknot's upcoming album, '.5: The Gray Chapter,' hints that Weinberg will replace former drummer Joey Jordison, who split from the band last December.
