Laura Byrne and Matty J just announced their third baby in the cutest way.

Laura Byrne and Matty J are expanding their family once again, announcing they're expecting baby number three. And they did it in the sweetest way possible.

The beloved Bachelor success story shared the joyful news on Instagram, but it was their four-year-old daughter Lola who stole the show.

In the oh-so-cute video, a smiling Lola makes the grand announcement.

"Hi everyone, I got a baby in my mum's tummy and I'm so excited," she says as she runs around the house smiling.

"I'm so, so, so, so, excited."

There's a bit of toddler babble we can't quite discern, but the little announcer continues, "I'd really like it to get a baby out. It's coming out today! Not really. But I'd really like the baby to come out."

"It's not coming out … but I really love it."

Watch the cute announcement. Post continues below.

And Lola's not the only one excited about the news.

Laura captioned the post: "We are SO SO SO EXCITED!!!! Johnson #3 under construction."

Ahhh, our hearts!

Turns out, Laura found out she was pregnant while Matt was in the I'm A Celebrity Jungle — and she shared all the goss on her podcast, Life Uncut.

Laura said she's 18 weeks pregnant and has been keeping the secret for some time.

"I found out very early on with this pregnancy," she said.

"One of my girlfriends was like, 'Wouldn't it be funny if you found out you were pregnant when he's in there?' She didn't really know that we were trying. And I was like, 'Ah, that's actually a possibility'."

Laura walked upstairs and peed on the stick, expecting it to be nothing.

"Then I looked at the stick and I was like, 'F**k off, is that a line?'"

It was two days after Matt had left for the jungle, meaning he had no phone and was completely non-contactable.

"I said to Laura that if I make it to the end of the jungle to tell me. If you find out you're pregnant while I am away, come onto the show and tell me," he said on his podcast, Two Doting Dads.

But ultimately, Laura decided to wait until after the show's finale aired.

"I didn't want to take away from an experience that he was having and kind of like experience top it with another thing, and I also wanted him to have some time to process what a huge thing he'd just been through," she said.

But first, listen to Laura talk about her family on Mamamia's But Are You Happy? Post continues below.

The couple's love story began on season five of The Bachelor, where Matty J chose Laura in the finale after his own heartbreak as runner-up on Georgia Love's season of The Bachelorette.

Their journey to parenthood hasn't always been smooth sailing. Early in their relationship, Laura experienced a miscarriage before becoming pregnant with their eldest daughter, Marlie-Mae.

"I felt so, so sad... and there was zero relief. And that was the realisation that we really wanted to be parents," Laura previously told Mia Freedman on the No Filter podcast.

"So we just threw caution to the wind, and I was soon pregnant again, this time with little Marlie."

Marlie was born two weeks overdue in June 2019 at the Royal Hospital for Women in Sydney. While the birth was complex and stressful, the family of three soon settled into their new life.

Then, they set their sights on baby number two.

Their second daughter, Lola, joined the family in February 2021, just 18 months after Marlie arrived.

They've spoken openly about the jump from one to two kids being intense.

"When Marlie was three months old, we took her travelling and I remember thinking, 'Oh, this having kids' thing is easy' Then Lola came along and smacked the stupidity out of us," Laura told Mamamia in an interview from 2021.

"Two kids is hard. Also, people expect you to know what you are doing with your second and because each baby is so different — you don't. Things I thought I had down with Marlie, I did not know what to do with Lola."

However, the family adapted to their new normal and have been thriving ever since.

Their daughters have become the centre of their world and, let's be honest, the stars of many a relatable parenting anecdote.

In 2023, the couple revealed they weren't entirely on the same page about expanding their family further.

"It's a big conversation that we've been having recently," Laura told Mamamia. "It's easy for me to say that I want to have another child because I'm not doing all the stuff Matt's doing."

At the time, Matty joked about Laura's suggestion for a third child after returning from a work trip: "My knee-jerk reaction is, 'What the f**k do you mean?!'"

But it seems the couple, who tied the knot in 2022, couldn't resist the pull of having another mini-Johnson running around.

"I think the reason why I would want to have a third is because I can't imagine there being a time when we don't have a toddler — I love age two so much. It's my favourite age that we've experienced so far, it's so funny," Laura previously shared.

The pregnancy news comes during an already hectic period for the couple.

Laura continues to juggle her jewellery brand ToniMay and her wildly successful podcast Life Uncut with Brittany Hockley, while Matty recently appeared on I'm A Celebrity Get Me Out Of Here Australia 2025 and co-hosts the Two Doting Dads podcast. They are also in the process of renovating their house.

Their announcement post was quickly flooded with congratulatory messages, as everyone praised the cutest announcement ever.

We'll be eagerly awaiting more updates as Laura and Matty J prepare to welcome their third bundle of joy in October!
