Sid Wilson has reportedly been ousted from Slipknot after serving as a key member of the heavy metal rock band for almost three decades. TMZ reports via a “source close to” Slipknot that the DJ and keyboardist was notified of his permanent removal from the group late Friday afternoon. It’s not yet known why Wilson, who had been a part of the group’s legendary “classic nine” lineup since 1999, was given the boot. Neither Wilson nor Slipknot have officially confirmed the reports at the time of writing. It comes a few months after Wilson quietly called off his engagement to fellow musician Kelly Osbourne in March, following his proposal at an Ozzy Osbourne show last year.
