Julia Roberts' Twins Just Turned 21 – Meet All 3 of Her Children

A quiet birthday post from Julia Roberts has drawn fresh attention to her growing family — and to how the actress views life beyond the spotlight.

Julia Roberts is no stranger to blockbuster moments — but this one may have just outshone her biggest red-carpet premieres. At 58, the "Leave the World Behind" star brought real-life drama to the 2025 Gotham Film Awards in New York, not for her career, but for a far more personal reason.

Her twins, Hazel Patricia and Phinnaeus Walter, have officially entered adulthood. That's right: the beloved children Roberts has fiercely shielded from the public eye are 21 years old.

And the Hollywood icon didn't hold back on what the moment meant to her. "Amazing" and "astonishing," she told Entertainment Tonight, summing up what it feels like to watch her babies grow into adults with voices and views of their own.

Throwback Shock – 'Game Changers' and 'Life Alterers'

To commemorate the occasion, Roberts shared a photo of her twins on Instagram. The picture, a throwback from when Hazel and Phinnaeus were just toddlers, struck a chord across social media.

Her caption? Packed with raw emotion and reverence. She called the twins "game changers" and "life alterers," adding that they were once just one year old — and now, miraculously, 21.

It was a glimpse into a private world fans have long speculated about. Roberts shares the twins with husband Daniel Moder, a cinematographer she wed in 2002. They also have a third child — Henry Daniel, born in June 2007 — who has likewise been raised largely away from the limelight.

'The Best Stuff' – Why Family Still Comes First for Roberts

Roberts' career may sparkle with Oscars and accolades, but she's never made it a secret: family is the role she cherishes most. In a 2022 sit-down with "CBS Sunday Morning," she laid it bare: being a Hollywood icon was a dream — but building a life with Moder and their children? That was "the best stuff."

She's long been vigilant about maintaining a protective bubble around her family. In a 2013 interview, Roberts explained why the public sees so little of her home life. She and Moder make a point to "protect" their kids and ensure their family experiences aren't filtered through a lens of public scrutiny.

The Queen of Privacy… Even at Disneyland

Even in places buzzing with paparazzi, Roberts has managed to stay under the radar. She once described taking her entire family to Disneyland without making headlines — no small feat for an actress of her stature. It was her first visit, and rather than being hounded by cameras, she spent the day riding attractions with her children in blissful anonymity.

That uncanny ability to blend in when it matters? It's part instinct, part ironclad boundaries. Roberts explained that she gives the public what feels appropriate, while fiercely guarding the sanctity of her family life. It's not a balancing act, she insisted — it's just "natural."

The House Rules That Keep the Roberts Family Grounded

When it comes to parenting, Roberts doesn't just go with the flow; she lays down the law. In a 2023 interview with Hoda Kotb on "TODAY," she revealed one of their household's core rules: phones go in a charging station the moment you walk through the door. At the dinner table? Absolutely no phones allowed.

Even now that her twins are away at college, Roberts keeps the same protective instincts intact. She still checks in — about sleep, health, and safety — urging them to send a text when they get home. Fame may follow her everywhere, but she's determined to raise her children like any other mom.

A Rare Glimpse Into Robert's Heart and Milestone Moments

Fans may recall when Roberts posted another throwback — on the twins' 19th birthday. At the time, she told Extra it was the perfect way to celebrate them publicly without compromising their privacy. The image, she said, struck the right balance: honoring the moment while respecting their boundaries.

In early 2024, the actress opened up even more, this time to Vogue, revealing how she was able to fully embrace motherhood after achieving early career success. By the time the twins arrived, Roberts had already conquered Hollywood. That meant she could hit pause on projects and be present, truly present, for her children.

Real Talk – Watching Her Friends Struggle Changed Everything

Roberts acknowledged how fortunate she was compared to her peers. She watched as other mothers juggled newborns and brutal work schedules, some pumping breast milk in office bathrooms, battling constant exhaustion.

That glimpse into their struggle made her even more grateful for the time she had at home. Still, she made one thing clear: while family always comes first, her creative passions remain essential.

Roberts said she hopes her children understand that her work adds meaning to her life, not subtracts from her commitment to them. It's not about choosing between being a mother and being an artist. For Roberts, it's all just part of who she is.

Fans Can't Believe Their Eyes – 'Time Flies!'

As with every rare peek into her private life, Roberts' birthday post for the twins' 21st birthday sparked an outpouring of emotion.

"How fast they grow! 🥰" wrote one follower. "They are all grown up! Wow time flies," commented another.

Dozens more chimed in with love for the family, with one message standing out, "You have a wonderful family ❤️."

It's clear that fans are hungry for more — but Julia Roberts, ever the master of mystery, will likely keep giving us only what she chooses to share.
