Naomi Watts and Liev Schreiber made a vow when they split. This proves they kept it.

We have seen some pretty ugly Hollywood breakups over the years. But there are some famous exes who know how to keep things amicable. Case in point: Naomi Watts and Liev Schreiber.

During their 11-year relationship, the actors welcomed two children, Sasha in 2007, and Kai in 2008. And despite parting ways in 2016, Watts, 56, and Schreiber, 57, continue to co-parent and support each other very publicly.

They also promised to put their kids first.

"We're doing things very differently. I'm pretty proud of us, corny as that may sound," Watts told Net-a-Porter in August 2019. "We've made it our absolute priority to be good and kind to each other and we're absolutely committed to that."

And committed they are. Just yesterday, the parents reunited to mark their son Sasha's high school graduation, sharing photos from the special day.

"You did it @sashapeteschreiber !!! Congratulations 🥳🤩⚡️💥🎉. My heart ♥️ California here you come!" wrote Naomi on Instagram, along with a slew of photos from the ceremony.

On his own page, Liev wrote "The graduate!!!" alongside a photo of the family.

Both tributes were quickly flooded with messages of support.

"Congratulations! Beautiful extended blended family! ❤️🙌," one follower wrote.

It's not the first time the exes have reunited for a school graduation. In 2022, Naomi and Liev, along with their new partners, celebrated their daughter Kai's middle school graduation.

"Modern family," Naomi wrote as a hashtag in the caption.

The actor has kept her current relationship with actor Billy Crudup relatively quiet, but they are said to have started dating in 2017. Three years later, during his Emmy acceptance speech for The Morning Show, Billy acknowledged Naomi's kids for the first time, saying, "I love you, and thank you."

Then, in 2023, Naomi confirmed she and Billy had wed, sharing a photo on Instagram of the pair outside a courthouse. The wedding was followed by a second ceremony in Mexico City the following year.

Liev, meanwhile, is married to former pageant queen Taylor Neisen. After marrying in July 2023, they welcomed a daughter named Hazel Bee. The parents announced her arrival via Instagram, writing: "Mom and baby are both super happy and healthy. Thanks to all for the love and support."

And, because she is a member of the coolest blended family ever, Naomi commented: "We love baby Hazel!!"

A year prior, she also wished Taylor, who she affectionately called "Tay", a happy birthday on Instagram.

Liev has previously emphasised the importance of "supporting each other" when it comes to co-parenting with Naomi.

While appearing on Sunday Today with Willie Geist in 2018, the Perfect Couple star recalled a time when he "was making jokes" about his ex-wife in front of his children, explaining that their "eyes light up when I talk about her".

"You can see how important it is to them that their parents care about each other," he said.

It's also clear that Sasha and Kai have fun with their parents. In 2020 they shared a TikTok where they made their mum and dad perform a dance, and both actors embraced the routine with gusto.

From silly dances to school graduations, it's clear that Naomi and Liev are their children's biggest cheerleaders.

If that's not fantastic co-parenting, we don't know what is!
