How Old Was Mila Kunis In That 70 Show

Mila Kunis Was Basically a Baby Playing a Baby on That '70s Show

Here's a fun fact that might wreck your brain a little: Mila Kunis was only fourteen years old when she walked onto the set of That '70s Show and pretended to be a sassy, Valley Girl teenager. Yep, you read that right. A literal teenager was playing a teenager, and honestly, it kind of makes the whole show feel like one giant inside joke.

The series premiered in August 1998, and Mila was born on August 14, 1983. So picture this — she was barely old enough to drive, let alone act like she had any idea what a '70s kid was supposed to be. Yet there she was, sipping fake beer and giving Topher Grace attitude, looking like she could barely see over the kitchen counter.

The Math Is Absolutely Wild

Let's do a little mental math that makes your head spin. The show was set in the 1970s, but it was filmed in the late '90s. Mila Kunis was born in 1983, which means she wasn't even alive yet during most of the decade the show pretended to take place in. She was born twelve years after the show's supposed setting ended. So when Jackie Burkhart was waxing poetic about the '70s, Mila was probably still watching Barney & Friends at home.

It gets even wilder when you think about the rest of the cast. Topher Grace was born in 1978, so he was about twenty when the show started. Ashton Kutcher was born in 1978 too. Danny Masterson was born in 1976. These guys were actually twenty-somethings pretending to be high schoolers, while Mila — the youngest cast member — was the only one who was genuinely the age she was playing. The irony is so thick you could spread it on toast.

Jackie Burkhart: The Icon Nobody Expected

Mila's character, Jackie Burkhart, was supposed to be the spoiled, popular, dramatic queen bee of the friend group. She was dramatic, she was hilarious, and she was incredibly annoying — which, honestly, sounds like a role a fourteen-year-old would nail without breaking a sweat. And she did.

The character was written to be a seventeen-year-old, but Mila was playing someone two years older than herself. You could argue Jackie looked younger than fourteen anyway, so the casting directors got away with one of the greatest deceptions in television history. Nobody questioned it. Nobody batted an eye. And that's the beauty of it.

She Stayed on the Show Way Longer Than Anyone Expected

That '70s Show ran for eight seasons, from 1998 to 2006. That means Mila Kunis was fifteen when the show ended. Over those eight years, she went from a gangly kid with braces to a fully formed young woman who could deliver punchlines like a seasoned pro. By the final season, she was twenty-two years old playing a character who was supposed to be in her late teens. The aging process was real, and so was the talent.

Here's something that might make you feel old: Mila Kunis was born before the internet was mainstream. She was born before Google existed. She was born before most people even knew what email was. And yet, she became one of the biggest sitcom stars of the '90s and 2000s. The timeline honestly doesn't make sense, but it works.

The Show's Legacy Is Still Going Strong

Decades later, That '70s Show is still one of the most rewatched sitcoms on streaming platforms. New generations of viewers discover it every year and fall in love with Jackie Burkhart's ridiculous one-liners. Mila's performance holds up because she was genuinely young and full of chaotic energy — you can't fake that kind of sparkle.

It's also worth noting that Mila Kunis went on to have an incredibly successful career after the show ended. She starred in Black Swan, Friends with Benefits, and voiced Meg Griffin on Family Guy for over two decades. From a fourteen-year-old on a Fox sitcom to one of Hollywood's most respected actresses — that's a wild trajectory.

So, How Old Was She Really?

To put it simply, Mila Kunis was fourteen when That '70s Show began. She was fifteen by season two, sixteen by season three, and so on. By the time the series wrapped, she was barely legal. The entire run of the show was essentially a documentary of Mila growing up in real time, except she was also pretending to live in the 1970s the whole time.

Next time you binge-watch the show, just remember that the girl giving you attitude about prom and boyfriends was barely older than a middle schooler. Mila Kunis didn't just act like a teenager on That '70s Show — she was one. And honestly, that's what made Jackie Burkhart so perfectly, hilariously believable.
