Marilyn Manson is known for his eccentric lifestyle and intense performances, but even the most hard-core rock stars aren't immune to health scares.

Before Manson came on stage, co-headliner Rob Zombie told the crowd that Manson wouldn't be joining him for a scheduled duet during Zombie's set, because he wasn't feeling well.

"My dear friend Mr. Manson is feeling under the weather. He's probably on the bus feeling like crap. I need a partner for the next song so let's sing it really loud and make him feel better", Zombie told the crowd.

The 49-year-old rocker did eventually come on stage, but early into the set he ended up collapsing on stage. After performing a cover of The Eurythmics' "Sweet Dreams Are Made Of This," Manson toppled onto one of the stage monitors.

After just four songs, Manson had to cut the show short. There has been no update on the singer's condition, but it is the second time in under a month that he has had to cancel a show. On July 26, Manson and Zombie canceled a show in Toronto.

"Marilyn Manson was unable to perform on his and Rob Zombie's Twins Of Evil tour in Toronto last night due to the flu," a statement on Twitter said. "Manson is recovering and is set to perform at all scheduled dates starting tomorrow at Heavy Montreal."

As of now, there is no word as to whether or not the remaining tour dates will be fulfilled. All indications point to the collapse stemming from an ongoing illness, as photographers were told to exit the press pit prior to the show because Manson didn't want to be photographed while ill.

Though a collapse on stage is terrifying, it's nothing compared to what Manson dealt with in 2017. During a show in New York City, Manson was crushed by a stage prop while performing. He had to cancel nine shows and required surgery for his injuries.

"[The prop] started to fall and I tried to push back and I didn't get out the way in time," he said of the accident. "I'm not sure what I hit my head on, but it did fall onto my leg and break the fibula in two places. The pain was excruciating. It definitely could have crushed my skull and my ribs. I have some minor bruising in that area, but it took six guys to pull it off of me. It was like wrestling a giant iron monster."

No updates on the singer's current condition have been released, but he is scheduled to perform tonight in Denver. One way or another, answers will come out.

We hope Manson's condition is not something serious and that he is able to play out the rest of his tour!
