Congratulations are in order for the model mother, 29, and her 40-year-old husband.
According to The Sunday Telegraph, Lara and Sam welcomed their second bub, a son, "a few weeks ago" but have so far stayed tight-lipped on confirming their little one's name.
It's believed Lara's mother, Sharon Bingle, flew into New York earlier in the month to help her daughter and meet her new grandchild.
The precious bundle of joy is the couple’s second child together, after they welcomed little Rocket Zot in March last year.
The pair have made no secret of wanting a larger brood following the birth of their first son, and will no doubt be thrilled for their little one to finally have a sibling to play with!
Speaking recently to Today Extra, the stunning star revealed that she hopes to grow her family with her high-profile husband.
"I would love to have more children, definitely," Lara said to the hosts, when asked about her plans for more babies in the future.
In the same telling interview, the Sydney local also spoke candidly about her son, whom she says is very advanced for his age.
"He walked at 10 months, he’s almost running now!" she bragged.
"He’s an Aries baby," she continued. "He’s quite strong, so when he doesn’t want to eat something, he doesn’t want to eat it."
And Lara’s latest addition won't be the last of them either. The founder of The Base makeup and skincare line has previously revealed on the Kyle and Jackie O show that she wouldn't mind having four kids, "sooner rather than later"!

"The more the merrier!" she said to the radio duo. "I have one brother and Sam has one sister so I think I want, like, a bigger family!
"Sam’s sister has three kids, which I just love and it's just like a big family, you're like a big team, she gushed. "It's awesome!"
Earlier this year, the Aussie icon opened up to InStyle about how her family will change after welcoming a second child.
“I had a great pregnancy with Rocket and touch wood it will be the same this time,” she revealed to the magazine.
“I’m sure it might seem full-on at the beginning,” she said of having two children so close together in age.
“It’s probably a lot harder than it is now, but when they get older they can share a life together,” she gushed.
Congratulations, you two! We can't wait to get to know your sweet new bub.
