The 34-year-old model welcomed son Hart 10 months ago and also shares 8-year-old son Flynn with ex-husband Orlando Bloom.
“Miranda, Evan, Flynn and Hart are looking forward to welcoming the newest member to their family”, a spokesperson told the publication.
Kerr recently opened up about family to InStyle Australia.
"My team understands that my family comes first—I’m going to come into the office after I drop my son to school, [or] do a conference call when my little baby is napping," Kerr said. "When people know what to expect, you can manage those expectations. It’s also important that my kids see that I’m a working mum and I have my own business and that their dad has his own business and we both work hard and money doesn’t grow on trees!
"Of course you want to spoil them, [but] that’s how my parents raised me and that’s why I have the work ethic [that I do]."
