The shoe designer and her TV star husband are yet to publicly confirm they are expecting.
However the 45-year-old recently took to Instagram to poke fun at rumours the pair are expecting by sharing a paparazzi photo of himself making his way out of the water while on holiday in Byron Bay.
“After a great deal of speculation … the rumours are true,” he wrote on the social media platform along with the baby emoji.
Stefanovic shares kids Jackson, 19, Ava, 13, and River, 12 with ex, Cass.
Karl is ensuring to spend some quality time with his other children before he becomes a dad for the fourth time with his second wife.

Jas recently showed off her blooming baby belly as she, Karl and Ava watched the second round match between Australia’s Ashleigh Barty and Slovenia’s Polona Hercog together.
The trio were all smiles as they watched the match.
