Fans went wild for the adorable picture in the comments section.
"Well trained," laughed one.
"So cute. And nice kitchen," remarked another.
One even joked: "Do you rent him out? I’d love someone that adorable to bring me my coffee each morning."
Lara, who is also mum to Rocket, born in 2015 and Racer, born in 2016, recently moved back to Australia from the US with her family.
The reason behind the move was due to Lara's actor husband Sam Worthington scoring a role in the Sydney Theatre Company’s production of Appropriate.
Former model Lara is well and truly settled back in her original home and previously revealed that her children are number one.
"At this stage of my life, with my sons as the total priority, I'm focused on wellbeing, motherhood and taking care of my family," she told Body + Soul.
Lara recently admitted she’s more confident with her body now than she was in her younger years.
“Before I had kids, I was always trying to get skinny or be a certain weight,” she admitted to Marie Claire.
“My mind was so focused on that, and then the moment I just let myself be happy in my body and had kids, it really changed for me.”
The model added that she felt as if the entirety of her early 20s were centred on body issues.
“Having a baby changed my body for the better. It’s like my body was meant to have kids, and maybe that’s why I’ve had so many and would happily have more!”
