1. Dave Grohl faked his broken leg

In 2015, Dave Grohl broke his leg during a Foo Fighters concert. He later made his return, continuing the tour on a custom-built throne. It didn’t take long for some to theorize that Grohl faked breaking his leg to boost ticket sales. Grohl later commented on its premise during a stop on the band’s tour.

“I’m really into the idea of a conspiracy theory,” he continued. “I think it’s fuckin’ rad. What if—what if I didn’t break my fuckin’ leg? What if I jumped offstage and I fell on the ground, and I made it all look like it was a fuckin’ emergency? And then they dragged me off to the side, and the band keeps playing, and then 10 minutes later, I magically fucking reappear onstage? Then, I get somebody else’s X-ray of a broken leg, and I make it into a T-shirt, and we make millions of fucking dollars. I design this fucking awesome throne so I don’t have to fucking stand up anymore! Imagine that!”

2. Andrew W.K.

One long-time circling conspiracy theory involves Andrew W.K. and how he doesn’t actually exist. There are those who believe W.K. is the product of industry bots who sought to create the ideal frontman. Of course, this party-loving and always trolling artist has done nothing to dispel the rumors. In 2015 during an interview with Larry King, W.K. was asked if he was a member of the Illuminati. “Not formally,” he replied, sending conspiracy theorists into a frenzy. The concept often revolves around someone named Steev Mike who’s one of many who supposedly portrays W.K. and is actually Dave Grohl.

3. Avril Lavigne died and was replaced by a look-alike

There are some crazy details that go along with this one. But to sum up it up, Avril Lavigne allegedly died in 2003. She was then replaced by a look-alike named Melissa in order to keep her promising career going. It sounds crazy and far-fetched, but there are plenty of theorists out there who aren’t afraid to go deep with these claims. In fact, the conspiracy theory is so popular that Lavigne herself has even chimed in on it—or was it, Melissa?

4. Pete Wentz died in 2010 and was replaced by a clone

Similar to the Avril Lavigne theory, this one has Fall Out Boy’s Pete Wentz dying in late 2009 or early 2010. The proof? The narrator for the YouTube channel Dead Celebrities & The Illuminati” claims “overnight, he was no longer cute,” referring to how he lost the bangs and eyeliner. The best part about this crazy theory? Apparently, all of Fall Out Boy are dead, with Wentz being the last one to pass.

5. Oh, and everyone in My Chemical Romance is dead, too

These death theories just get crazier and crazier. This video claims the Way brothers are actually the Way sisters, Gerardine and Michelle. It also states “everyone in the industry is transgender pretty much” and “one time there were real people [in the industry], although they were in the minority, but now there’s nothing but clones with demons inside.” If their clones can’t play instruments, it may explain why we haven’t had an MCR reunion yet?

6. David Bowie predicted the rise of Kanye West

This theory kicks off with David Bowie’s 1972 album, The Rise And Fall Of Ziggy Stardust And The Spiders From Mars. If you look at the album cover, you’ll notice Bowie standing under a sign that says “K. West.” The opening track is “Five Years,” which predicts the end of the world unless a “Starman” comes to Earth and saves us all. Five years after the album dropped, Kanye West was born. It doesn’t stop there—Bowie’s final album, Blackstar, allegedly confirms West as his chosen successor on the title track by singing, "Something happened on the day he died/Spirit rose a metre and stepped aside/Somebody else took his place and bravely cried/I'm a blackstar, I'm a blackstar."

7. The blood of KISS ended up inside Sports Illustrated

From selling air guitar strings to a casket, KISS have never been ones to shy away from unique merch and dark humor. This theory puts a new spin on the fact that the band added vials of their own blood to the red ink that was to be used for their Super Special KISS comic book in 1977. Supposedly, a mix-up caused the blood-tainted red ink to be used in a run of Sports Illustrated magazines instead.

8. John Lennon was killed by Stephen King

This theory surfaces from Steve Lightfoot who believed horror writer Stephen King was the one to murder John Lennon. His claims come from a photo of Lennon taken the day of the murder. In it, he’s signing an autograph for Mark Chapman (who was convicted for Lennon’s murder). Lightfoot believes the man in the photo looks more like King. The argument falls in line with the ones where it’s believed that the government had a hand in Lennon’s death due to his outspoken anti-war stance.

9. Paul McCartney has been dead for years 

This theory dates back to 1969, suggesting the former Beatles member died in the mid-’60s. The death was allegedly covered up by hiring a look-alike. The weirdest part? Supposedly, the Beatles began leaving clues for fans to figure out the whole “scam.” While McCartney has denied the claims, it hasn’t kept the belief from continuing to circle to this day.

10. Jay-Z is a time-traveling vampire

While there are numerous theories surrounding Beyonce and Jay-Z, one of the craziest is the idea of the rapper being a time-traveling vampire. The concept surfaced after a 1933 photo taken in Harlem found its way to the internet. In it, one man looked an awful lot like Jay-Z. The rapper wasn’t born until December 1969, so clearly the only excuse is that he’s a time-traveling vampire.
