You know that feeling when you see a face on TV and it feels like a warm hug from your childhood? That's Juliet Mills. Whether you remember her floating into the Everett household in Nanny and the Professor or causing supernatural chaos as Tabitha the witch on Passions, she's one of those rare stars who has just... always been there. But lately, everyone seems to be asking the same thing: how old is Juliet Mills exactly?
Honestly, the answer might surprise you because she’s been working since she was literally an infant.
The Current Age of Juliet Mills
As of early 2026, Juliet Mills is 84 years old. She’ll be hitting the big 85 on November 21, 2026.
It’s kind of wild to think about, but she was born in 1941. That was right in the middle of World War II in London. Her parents—the legendary actor Sir John Mills and the playwright Mary Hayley Bell—actually had to move the family to the countryside just to get away from the Luftwaffe bombing raids. Talk about a dramatic entrance into the world.
She isn't just "still around," either. She's active. You’ve probably seen her popping up in recent projects like the movie Poolman or even doing voice work in Metalocalypse: Army of the Doomstar. She hasn't slowed down much, which is probably why people are so curious about her age—she still has that same spark she had in the 70s.

Growing Up as British Acting Royalty
If you think your family is high-achieving, Juliet’s childhood was on another level. We're talking "godmother is Vivien Leigh" levels of Hollywood royalty. Her sister is Hayley Mills, the Parent Trap icon. Her godfather was Noël Coward.
Basically, she didn't just choose acting; she was born into it.
Her first "role" was in the 1942 film In Which We Serve. She was 11 weeks old. Seriously. She played a baby in a movie starring her own father. By the time she was 18, she was already nominated for a Tony Award for Five Finger Exercise. Most 18-year-olds are worrying about prom; Juliet was conquering Broadway.
The Maxwell Caulfield Factor
One reason Juliet stays so "young at heart" might be her marriage. This is a story people still talk about because it broke all the "rules" of the time. In 1980, Juliet married actor Maxwell Caulfield (you know him from Grease 2 and Empire Records).

People gossiped. They whispered. They predicted it wouldn't last a year. Fast forward over 45 years later, and they are still one of the most solid couples in Hollywood. They live in Ojai, California, where they tend to a massive rose garden and grow their own fruit. Juliet has always said that age is just a number and that "there are no rules" when you find your person. Seeing them together in 2024 performing Love Letters on stage proved that the chemistry is still very much there.
Why We Are Still Obsessed With Her
It isn't just about how old Juliet Mills is; it’s about the career she’s built across eight decades. Most actors get a "peak" and then fade away. Juliet just reinvents herself.
- The Sitcom Era: Nanny and the Professor (1970–1971) made her a household name in America. She was the "British Mary Poppins," and everyone loved her.
- The Serious Actor: She won an Emmy in 1975 for QB VII. She wasn't just a pretty face; she had the chops.
- The Cult Favorite: Then came Passions. Playing Tabitha Lenox for nearly a decade introduced her to a whole new generation of fans who didn't know anything about her 1960s films. She leaned into the camp, the talking doll (Timmy!), and the sheer absurdity of daytime soaps with total grace.
What You Can Learn From Juliet’s Longevity
Looking at Juliet Mills at 84, there’s a clear takeaway for the rest of us. She’s never tried to hide her age or pretend she’s someone she’s not. She moved from ingenue roles to "nanny" roles to "witch" roles to "grandmother" roles without losing her identity.
She often credits her energy to her lifestyle in Ojai and her long-standing romance with Maxwell. But mostly, it seems to be about gratitude. In recent interviews, she’s talked a lot about just being happy to still be invited to the party.

If you're looking to follow in her footsteps—maybe not the acting part, but the "aging gracefully" part—here is the unofficial Juliet Mills playbook:
- Ignore the "Gap": Whether it's an age gap in a relationship or a gap in your resume, don't let it stop you.
- Keep Moving: Whether it's theater tours or gardening, staying physically active is non-negotiable.
- Embrace the Pivot: Don't get stuck trying to be who you were at 25. Every age has a different "role" to play.
Juliet Mills remains a class act. While the internet might keep searching for her age, she’s busy living it, usually with a pair of gardening shears in one hand and a script in the other.
Keep an eye out for her upcoming guest spots—she’s been rumored to return to Grey’s Anatomy in the next season, proving that 84 is just the beginning of another chapter.
Next steps: If you're a fan of classic TV, go back and watch the pilot of Nanny and the Professor—it’s a masterclass in charm. Or, if you want to see her range, find a clip of her 1975 Emmy-winning performance in QB VII to see a totally different side of her talent.
