You’ve probably seen the photos. Two guys with the same messy hair, the same wide grin, and that specific Pittsburgh energy that’s hard to replicate. It’s led to a massive amount of speculation over the years. Does Mac Miller have a twin brother? Honestly, if you scroll through old Reddit threads or deep-dive into fan theories on TikTok, you’ll find people convinced that there’s a secret "other" McCormick out there.
The truth is a little less "parent trap" and a lot more grounded in reality.

Mac Miller, born Malcolm James McCormick, did not have a twin. He had a brother, yes, but they weren't twins. His only sibling is an older brother named Miller McCormick.
The Mystery of Miller McCormick
It’s easy to see why the confusion happens. First off, look at the names. Mac Miller’s professional name literally uses his brother’s first name as the last name. That’s a recipe for a Google search disaster right there. Malcolm took the name "Miller" as a tribute to his maternal grandmother’s maiden name, but it also happened to be his brother’s name.
They looked incredibly alike. Not "same DNA" alike, but definitely "same household, same genes" alike. Miller is about two or three years older than Malcolm. When they were younger, the resemblance was even more striking. They both had that lean build and the same expressive eyes that made people double-take.
But no, they weren't twins.

Who is Miller McCormick, actually?
While Mac was the one on stage in front of thousands of screaming fans, Miller was often the one behind the scenes making sure the visual side of the "Mac Miller" brand looked as good as the music sounded. Miller is a highly talented graphic designer and artist.
If you own a physical copy of Blue Slide Park, Watching Movies with the Sound Off, or GO:OD AM, you’re holding Miller’s work. He designed the album art for almost all of Mac’s major projects. He wasn't just a "brother of a famous person"; he was a vital part of the creative engine.
They were close. Incredibly close.
Miller once shared a story about sitting by the window in the hospital right after Malcolm was born. It’s his first real memory—sitting there while their mom’s nurse brought around some mint jelly. It’s those small, human details that remind you these aren't just celebrities; they’re just a family from Point Breeze.
Why the Twin Rumor Won't Die
Internet rumors are like weeds. You pull one, and three more pop up because someone saw a blurry photo from 2012.
The "twin" theory usually stems from a few specific things:
- The Pseudonyms: Mac was obsessed with alter egos. Larry Fisherman, Delusional Thomas, Larry Lovestein. For a casual fan, seeing "Malcolm McCormick" and "Miller McCormick" on the same credit list looks like a glitch in the matrix.
- The Music Videos: In some of his earlier work, Mac used mirrors and editing tricks to appear as multiple versions of himself. If you’re half-watching a video while scrolling your phone, you might think, "Oh, he has a twin."
- The "Wiz Khalifa" Factor: Early in his career, Mac often referred to Wiz Khalifa as his "big brother." They weren't related, obviously, but the hip-hop terminology confused people who took everything literally.
In reality, the McCormick household was just the two boys. Their mom, Karen Meyers, was a photographer (which explains where the artistic genes came from), and their dad, Mark McCormick, was an architect.
The Role of the "Other" McCormick Today
Since Mac’s passing in 2018, Miller has become a bit of a guardian for his brother's legacy. He doesn't do a lot of interviews. He’s not out there trying to chase the spotlight. But when he does speak, it carries weight.
For instance, back in 2021, there was a movie being made by Machine Gun Kelly originally titled Good News. It was loosely based on a "troubled musician," and the title was a direct reference to one of Mac’s most emotional posthumous tracks. Miller didn't hold back. He went to Instagram and basically told them to keep Mac’s name—and his songs—out of it.
The producers eventually changed the title. That’s the kind of influence Miller has. He isn't a twin, but he’s the keeper of the flame.
He was also heavily involved in the 2025 release of Balloonerism. That project was a "holy grail" for fans for a decade. It’s a weird, experimental, beautiful mess of an album recorded mostly in 2014. Miller helped ensure that when it finally came out, it wasn't just a cash grab. It was art.

Mac was the "atom bomb of light," as Miller once described him. He was always moving, always cracking jokes, always the loudest person in the room (in the best way possible). Miller is more reserved. He’s the guy in the back with the sketchbook, watching everything happen.
They had different paths, but they ended up in the same place: making stuff that people actually cared about.
