Julia Roberts shares sweet tribute as her twins Hazel Patricia and Phinnaeus Walter turn 19

It's always nice getting a little glimpse into the family lives of our favourite celebs.

Now, while Pretty Woman star Julia Roberts is fairly private when it comes to her personal life, she's just shared an incredibly touching sweet tribute of her twins, Hazel Patricia and Phinnaeus Walter, as they turn 19 today (29 November).

The 56-year-old Hollywood A-lister took to Instagram to share with her 11.7 million followers a black and white throwback of her cradling the two tots on her lap.

She captioned the heartwarming post: "✨✨19✨✨ There are no words for the joy, the fun, the wild rumpus of life together."

One fan commented: "Happy birthdays to you all!!"

A second penned: "Happiest birthday to both of you ! Lots of love!"

"Wow 19!!!! Happy birthday!!!!" echoed a third.

The Eat, Pray, Love actor, who also shares 16-year-old son Henry with husband Daniel Moder, previously opened up about her experiences with parenthood.

"I think it's our personal responsibility to advocate for ourselves, and I think that my husband and I both are people of strong convictions and opinions and compassions and I think that we try to instil that in our kids as much by example as by preaching," she told E!.

Roberts added: "It's an interesting society and culture that they're coming to age within, and I think that... they bear a huge responsibility—more than I think I did at their age—to speak their minds and speak up for themselves and advocate for the things that they believe in."

The pair first met decades ago on the set of the 2001 film, The Mexican, and tied the knot a year later.

A few years back in 2018, the Notting Hill star opened up about her domestic life on Gwyneth Paltrow's the Goop podcast.

Talking about her marriage, she explained: "It just gets deeper, it just gets more complex.

"You're young and you fall in love and go, 'Oh, yeah, we're going to get married and we're going to build a house and will have kids,' and all these things that we all kind of dream of, but you don't know if you're going to like the same couch, and you don't know if he is going to want to get, like, patterned towels.

"Then, of course, the bigger ones are, will you parent in a way that has balance to it, that holds hands in philosophy?"

She continued: "You just don't know these things until you are right there doing it, and we are so fortunate that there is some kind of inexplicable harmony to the way we do things, because we do things differently .... but there's something together that makes all the sense in the world."

Roberts added: "The best decision I ever made in my entire life was to hitch my wagon to Danny Moder."
