Who are Mikey Madison’s four siblings? All we know as Oscar winner introduces twin brother on SNL

The 2025 Best Actress Oscar winner, Mikey Madison, guest-hosted the recent Saturday Night Live episode. During her monologue, the Anora star also introduced her brother, Miles, by poking fun at him.

Miles Rosberg is Mikey Madison’s twin and one of her four siblings. The award-winning actress previously talked about her “psychologist” parents and siblings during a 2017 chat with Interview Magazine. Mikey told the publication,

“My parents are psychologists. My father is a specialist with schizophrenia and my mother works with mostly children. I have four siblings, two older sisters and two brothers. One of them is my twin. I’m the only actor in the family.”

Mikey Madison’s twin brother, Miles Rosberg, has been a high school and collegiate athlete for Sierra Canyon School and the University of California. He served as the captain of the Cal Men’s lacrosse team in 2021 and majored in Data Science and Mathematics.

Mikey’s younger brother is Holden Rosberg. According to her conversation with Interview Magazine, her youngest sibling did parkour. Like Miles, Holden also represented Sierra Canyon School in high school athletics.

The Once Upon a Time... in Hollywood actress also has two older sisters – Natasha (aka Tatie) and Tanya. Natasha is married to actor-writer-producer Jeff Howard of Big Smits Entertainment. Mikey is the only actor among her siblings, and her older sister’s marriage to Jeff was the motivation behind her career choice, she told Interview Magazine,

“My sister married a writer, so I think that’s what sparked my interest in acting.”

Mikey Madison’s other sister, Tanya, manages a business in Thousand Oaks. She owns The Hair Extension Place, which deals in hair extensions and supplies.

“I’ve always been really close with all my siblings, and actually, my twin brother is here to support me. Let’s see if you can guess which one of these guys is my twin brother.”

After Miles appears with three other men on the screen, Mikey Madison adds,

“If you guessed the one who looks like Ron Weasley on testosterone, you win!.”

Miles Rosberg was also present by her sister’s side when she won an Oscar earlier this month. After the announcement, the siblings embraced before Miles handed Mikey her acceptance speech. On the stage, the Scream actress gave a shout-out to her family, alongside her twin brother,

“Thank you to my incredible family. My mom and my dad and my sister and my little brother. And my twin brother, Miles – Thank you for being my best friend, not that you have a choice.”

Mikey Madison spoke to USA Today about being nervous about her family watching her performance in Anora, highlighting the subject matter it dealt with. She talked about her brother’s reaction when he saw the film,

“I was nervous about my family seeing it because you want them to like your work. My twin is my closest friend, so I was able to ask him, ‘Did you like it? Do you think I’m a good actor?’ It’s embarrassing to even admit that, but he was speechless when he saw it for the first time.”
