You’ve probably seen the name Mikey Madison everywhere lately. Between her gritty, high-octane performance in Anora and her recent Best Actress win at the 2025 Oscars, she’s officially Hollywood’s newest obsession. But if you’ve been scrolling through social media or watching her award acceptance speeches, you might have noticed a recurring name that isn't a director or a co-star.
His name is Miles Madison. And yeah, he’s her twin.
The internet basically had a collective "wait, what?" moment when Mikey introduced him during her Saturday Night Live monologue in March 2025. One minute we’re talking about her intense method acting, and the next, everyone is thirst-posting about her brother who looks like, in her words, "Ron Weasley on testosterone."
So, Who is Mikey Madison’s Twin Brother?
It’s rare to find a celebrity twin who isn’t also in the industry, but Miles seems pretty content staying out of the "actor" lane. Born on March 25, 1999, in Los Angeles, Miles and Mikey are part of a massive, tight-knit family of five siblings. Their parents, Michael and Tracy Rosberg (Mikey’s real last name is Rosberg), are both psychologists.
That might explain why Mikey is so good at getting into the heads of her characters.

Growing up in the San Fernando Valley, the two were inseparable, though they didn't always act like it. Mikey actually told W Magazine that back in high school, Miles used to pretend they weren't even related. Imagine being at the same school as your twin and just... ignoring them? He’d wait until the very last day of school to tell people, "Oh yeah, that’s my sister," usually when someone caught him getting into her car.
The SNL Moment That Went Viral
When Mikey hosted Saturday Night Live, she didn't just mention him; she put him front and center. During her monologue, she joked about the family dynamic and then pointed him out in the crowd. The camera panned to a guy with striking red hair—a sharp contrast to Mikey’s dark, brunette features.
The internet did what the internet does.
Within minutes, "Mikey Madison twin brother" was trending. People were shocked by the lack of resemblance, which is common for fraternal twins but still trips people up. He’s got that classic ginger look, while Mikey has that distinct, dark-eyed intensity we saw in Once Upon a Time in Hollywood and Scream.

Why They Look So Different
Fraternal twins are essentially just siblings born at the same time. They share roughly 50% of their DNA, just like any other pair of siblings. In their case, Miles clearly took after the side of the family with red-hair genes, while Mikey leans into the darker, Ashkenazi Jewish features of their heritage.
A Bond Forged in "Anora"
Beyond the viral looks, the relationship between Mikey and Miles is actually pretty wholesome. During the press circuit for Anora, Mikey admitted she was terrified of her family seeing the film. If you've seen it, you know why—it’s raw, explicit, and incredibly vulnerable.
She leaned on Miles for the ultimate "vibe check."
She told USA Today that he is her "closest friend" and the person she trusts most for an honest opinion. After he watched the movie, he was reportedly speechless. He told her, "I didn't see you at all; I just saw the character." For an actor who just swept award season, that’s probably the highest praise she could ever receive.

The Rest of the Family
While the twin connection gets the most headlines, the Madison/Rosberg household is a full house.
- The Sisters: Mikey has two older sisters. One of them married a writer, which Mikey says actually helped spark her interest in the arts.
- The Little Brother: There’s a younger brother named Louis who apparently does parkour.
- The Parents: Having two psychologists for parents (her dad specializes in schizophrenia) meant the kids were encouraged to be "people-savvy" and emotionally connected from a young age.
What Miles Madison is Doing Now
Unlike Mikey, who was a "weird horse girl" (her words!) before becoming a film buff and actress, Miles hasn't pursued the screen. At the Vanity Fair Oscar Party, he told reporters that they were even delivered via C-section at the exact same time so they wouldn't have to argue about who was older.
He seems to be her biggest fan, showing up at every major red carpet and event, but he isn't looking for his own IMDB page. He's the guy in the background making sure she stays grounded while she's winning Academy Awards.
Honestly, in a town like Hollywood, having a twin who knew you when you were just a kid obsessed with horses is probably the best anchor an actress could have. Whether he's being called "hot" by strangers on X (formerly Twitter) or giving Mikey notes on her Russian accent, Miles Madison is clearly a permanent fixture in the star's life.
If you’re looking to follow him, you might have a hard time. He keeps a relatively low profile on social media compared to his sister, though you’ll occasionally spot him in the background of family photos posted by their dad, Michael.
