Congratulations are in order for Sylvia Jeffreys and Peter Stefanovic, who just announced that they are expecting their first baby.

Mum-to-be Jeffreys shared the happy news on Instagram, with a photo of her and Stefanovic.

"We're having a baby boy and we're totally over the moon!! 💫," wrote the 33-year-old Nine Network presenter.

Stefanovic, 37, posted a similar message on his Instagram account, writing, "Soon to be a family of three and we are rapt! Good thing I'm already match fit with the whole no sleep thing 😁."

In Stefanovic's photo, he and Jeffreys are holding a card which reads "IT'S A BOY."

Friends and colleagues were quick to send their congratulations, with Bec Judd replying to Jeffreys' post with "Woohoo!!!!! Best news. Congratulations guys."

"Amazing news! Congratulations you two," commented Phoebe Burgess. "Big kiss xxx."

Sister-in-law Jasmine Yarbrough replied, "Best news ever."

Nine Network and 2UE presenter Ben Fordham left a comment on Stefanovic's post writing, "Holy. What. Wow. Congrats you two. You will make fine parents. Little fella will have the best of both worlds. Best news I've heard in ages."

Deborah Knight said, "Way to go Pete!! So happy for you and Sylv — best news."

The happy news comes two years after Jeffreys and Stefanovic tied the knot in a stunning ceremony in the New South Wales Kangaroo Valley in April 2017. They exchanged vows in front of an A-list crowd at the Ooralba Estate, a charming property in the Southern Highlands region. 

Months after the nuptials, Jeffreys told the Australian Women's Weekly that children were always in their future. 

"We'd love a house full of kids," she told the magazine.

Congratulations to the happy couple!
