AceShowbiz - Australian model Miranda Kerr is pregnant with her third child.

The KORA Organics founder welcomed Hart, her first son with Snapchat SEO Evan Spiegel, 10 months ago - and the couple is already expecting again.

A spokesperson for the model has confirmed the happy news to the Sydney Daily Telegraph, stating, "Miranda, Evan, Flynn and Hart are looking forward to welcoming the newest member to their family."

Miranda is also mum to eight-year-old Flynn, her son from her marriage to Orlando Bloom, who is making some big family plans too after asking his girlfriend, Katy Perry, to marry him on St. Valentine's Day, February 14.

Kerr recently opened up about the importance of her family in an InStyle Australia interview, revealing, "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. 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."

The model isn't bothered about getting back into shape now she's a mother - shortly after giving birth to Hart last year, she told Marie Claire Australia she's proud of her "mum-bod."

"It's really important as women that we're gentle with ourselves and don't feel like we have to snap back into shape after a baby... It's O.K., I've got a mum-bod and it's fine! I don't mind. It's all part of it," she said. "I took nine months - well, 10 months - to grow a beautiful child and it might take 10 months to feel good in a swimsuit again. Or longer. Or never... I love being a mum, it's the most rewarding thing."
