Marilyn Manson arrives at the world premiere of "King Arthur: Legend of the Sword" at the TCL Chinese Theatre on May 8, 2017 in Los Angeles.

The goth rocker's latest jab suggests any possible collab is now off the table.

Marilyn Manson’s rocky relationship with Justin Bieber took another turn in a recent interview where he told The Scully Show that he doesn’t know why the pop star wore his merch “because I don’t know how to use the mind of a squirrel.”

“He’s in some sort of sexual religious cult with an Asian version of Dave Navarro, apparently,” Manson said of the “Sorry” singer. “The guy doesn’t wear a shirt... But no, I don’t like to fight with girls, so I don’t want to fight with Justin Bieber.”

The shocker-rocker has an on-and-off beef with the Biebs, who once wore a Manson shirt on stage and later told the “Beautiful People” singer, “I made you relevant again.”

“I saw a little girl in a pink hoodie with blond hair, and it turns out to be Bieber,” the Antichrist Superstar previously told Billboard. “I sit down, and I say, “Hey, so you wore my shirt and everything onstage.” He was one of those touchy people that hit you when they talk, and he comes up to about dick height.”

The two briefly reconciled last month when Bieber apologized to Manson over text, the latter hinting at a possible collaboration. It's unclear how that unconfirmed project might withstand the rocker's latest jabs.
