Marilyn Manson, Rob Zombie could cut Twins of Evil Tour ties after trading threats at Detroit stop

Saturday afternoon update:

Rob Zombie confirms on Facebook he and

at DTE Energy Music Theater in Clarkston. It was unclear Saturday if the incident led to any arrests or injuries.

CLARKSTON, MI - Marilyn Manson and Rob Zombie certainly didn't play nice with each other Friday night at DTE Energy Music Theater, the ninth stop of a 36-city "Twins of Evil Tour."

And it had nothing to do the music that was played; apparently it had to do with what wasn't.

Manson and Zombie appear to have a serious beef with each other after Manson accused his fellow co-headliner of cutting his set short.



Once Zombie took the stage, he laughed off Manson's threat and appeared to give Manson the message he's either no longer welcome on the tour or has no shot of touring with him again once it ends.



If that wasn't enough, Zombie then fired more verbal shots at Manson's near the end of his own 90-minute set.

Zombie, paying homage to Detroit rocker Alice Cooper, covered Cooper's hit song "School's Out," and filled it with several cuss words directed at Manson.

"(Bleep) you Marilyn Manson!," Zombie yelled several times, along with other choice words including "suck it Marilyn Manson!"

Zombie not only cussed Manson out during the song, while Manson was nowhere in sight, but also called him "Brian," referring to Manson's birth name - Brian Warner.

The "Twins of Evil Tour" appears to have at least 27 stops left,

Based on Friday night's display of what appears to be an extremely tense relationship, it's hard to believe the tour will go on drama-free unless there's some sort of reconciliation.

Manson apparently also had beef with Zombie during Thursday night's tour stop in Rosemont, Ill., a Chicago suburb.

"Sorry to Chicago for not getting to play "Beautiful People," Manson wrote. "You can sing it in between Zombie songs, his band has already played it."

It's unclear how this Manson-Zombie relationship will work out, but I'll do my best in the coming days to keep you updated.

Despite the drama between the two shock rock showmen,
