Typically, it may be easy to pick a heavy metal fan out of a crowd — just look for the black Metallica t-shirt — but there are some celebrity metalheads that you would never expect.
Some are obvious, such as rapper/actor Ice-T, who actually has his own metal band, Body Count.
He may have gotten his start in rap before going on to star in NBC's Law & Order: Special Victims Unit, but Ice-T and Body Count have been putting out albums since 1992.
On their most recent album, Bloodlust, the frontman proudly states that legendary thrash band Slayer is one of his favorite groups.
Ice-T's history with metal music is well-documented however, and may not really come as a surprise.
If you're curious about who else in Hollywood might be a celebrity metalhead, scroll down for our list!
Maybe the most surprising name to many when talking about celebrity metalheads is pop singer Demi Lovato.
During a 2008 interview with MTV, the Camp Rock star named bands like Lamb of God, Job for a Cowboy, Maylene and the Sons of Disaster, and Abigail Williams. She also said that Norwegian black metal band Dimmu Borgir was one of her favorite live bands.
"It's so completely different from anything else," Lovato said of her love of metal at the time. "You've got vocals that I can't do, the double bass drums, the incredible guitar solos ... every part of the band does more difficult stuff than your average rock band does. I listen to these bands, and I wish I could do all of that, but I can't."
There's no word on if she has continued to follow metal into her 20s, but maybe she'll turn up doing vocals on a Mastodon album someday and we'll have our answer.
Game of Thrones fans know him as the lovable Hodor, from the HBO series based on George R. R. Martin's book series, but actor Kristian Nairn is also quite the music aficionado.
In addition to being an accomplished deejay, Nairn is also a lifelong metalhead who recently got to shred with '80s thrash icon Megadeth.
While attending the European Hellfest music festival, Nairn posted an Instagram video of himself jamming with Dave Mustain and the band, captioning it, "Sometimes I don’t know how things happen.. haha"
Sometimes I don’t know how things happen.. haha. My 14 year old and 42 year old self had a massive bucket list item checked off and got to play warm up with @megadeth yesterday.

"My 14 year old and 42 year old self had a massive bucket list item checked off and got to play warm up with [Megadeth] yesterday," he added. "The band that started my journey honestly."
Controversial rapper XXXtentacion died on June 18, 2018, leaving behind a vexed legacy of "art vs. artist."
One thing that is not debatable about the 20-year-old's past, though, is his love of heavy metal music, which he never denied was an influence on him.
A number of tracks that the rapper put out have clear metal elements ("King," "schizophrenia,") and he even sampled Slipknot on a track called "Off The Wall."
He also featured punk drummer Travis Barker (Blink-182, Transplants) on a track from his last album, ?, and appeared on very metal track from rapper Craig Xen titled "Crucify Thy Infant, Son of W—."
Jim Carrey is the type of personality that at first when you hear he's a metalhead you think, "really?" But once you think about it, it kind of makes perfect sense.
His affinity for metal has been documented as far back as one of his earliest appearances on the Arsenio Hall show in the early '90s when he talked about listening to British grindcore band Napalm Death.
Later, he managed to get another one of his favorite bands — Florida death metal legends Cannibal Corpse — into a scene in Ace Venture: Pet Detective.
In all fairness, Nic Cage being a metalhead is not all that surprising considering his son Weston Cage used to play in a black metal band, but it is pretty cool.
Not only was he a supportive dad when it came to his son's band, Eyes of Noctum, but Weston once said in an interview that his dad was also into some other iconic black metal bands.
"He likes Darkthrone and he likes Satyricon as well," Weston said of Nic's taste in metal, as reported by Metal Injection.
Michael Fassbender has starred in numerous film franchises, from X-Men to Aliens. Fans might be surprised to found out, though, that he's an old-school metalhead.
Metal Injection once reported that Fassbender gave an interview wherein he said that Metallica "was a big influence" in him growing up.
"Nowadays, people just listen to everything, it’s great, but back when I was at school, high school, you were a Goth or you were into grunge or you were into punk or you were into metal and that kind of defined your style — in what you wore and the groups you hang out with," Fassbender went on to say.
"I think in places, you know, growing up in the countryside, I think music is a very big deal for teenagers and especially in places away from cities. It’s kind of the one outlet you can get. There’s not a lot of options other than, you know, fields and mountains which are beautiful and great, but in terms of any action it was found through some sort of music," he added. "So yeah, heavy metal was big."
The outlet also noted that he is said to be a big fan of band like Sepultura, Iron Maiden, and Slayer as well.
Tom Hanks may often be referred to as the "nicest guy in Hollywood," but that didn't seem to stop his son Colin Hanks from becoming a bit of a metalhead.
During a podcast interview earlier in 2018, Hanks name dropped both Far and the Deftones as bands he was a big fan of growing up, eventually mentioning Primus as well.
"I was a big Primus fan growing up. I was obsessed with them… I was really drawn to them because they were so different. And that was really sort of like the big thing for me growing up," Hanks said, per Metal Injection.
Not many people realized that comedian Bill Burr is an avid drummer, and even less people know that he's a metal fan.
During a podcast in 2017, Burr mentioned that his drum teacher recommend he check out Meshuggah, which he did, but felt it was "too advanced" for him at the time. He eventually came back to the band later, and ended up becoming a big fan.
"I had this Meshuggah album for the longest time and I went back and listened to it and I think I’m finally starting to like… I always knew it was amazing but now I am actually f—ing into it." he said in the podcast, as reported by Metal Injection.
"I keep listening to that first song — I’m babystepping my way into it, this music is way advanced for my limited musical abilities," Burr added. "But that first song "Stengah" … the drumming on that, the whole f—ing thing is unbelievable."
Fans will know Glenn Howerton as Dennis from It's Always Sunny In Philadelphia and disgraced Harvard philosophy scholar Jack Griffin on NBC's A.P. Bio, but it turns out he's also into some pretty heavy metal as well.
On Twitter, a fan asked Howerton if he likes "any hard rock/metal" music, to which he replied that indeed he did.
"Gojira is amazing," Howerton said, mentioning the French technical metal band.
Gojira is amazing. Faith No More was the first band to make me appreciate how fun metal can be. https://t.co/qYRcDNwP3P— Glenn Howerton (@GlennHowerton) December 27, 2017
"Faith No More was the first band to make me appreciate how fun metal can be," he added.
