Teresa Palmer is expecting her fourth child

Posting a picture of herself cuddling her three kids – Bodhi, seven, Forest, four, and Poet, 22 months, whom she has with her husband Mark Webber – with her baby bump on show, she wrote: “35 years ago right around now I was born in sunny Adelaide. Today I am thinking of my mothers transition to motherhood and feel grateful to her for all she has done for me. I celebrate her, a healthy full life & the miracle of birth. Reflecting on this surrounded by my darling babies, including our newest little love @markwebber #wehavesomanychildren #thebestkindofbirthdaypresent (sic)”

And in a second post, Teresa thanked her fans for their love and support following the happy news.

She wrote: “Firstly thank you all for the baby and birthday love!! You’re all so thoughtful & loving and I’ve read ALL your comments (sic)”

Meanwhile, the ‘Warm Bodies’ actress recently explained how motherhood “liberated” her after a battle with orthorexia, which is described as an obsession with “proper or 'healthful' eating”.

She said: "My body just blossomed and I had this big belly and I could feel life within me, and it was just incredible seeing what my body could do. I was getting stretch marks on my boobs and cellulite all over my bum and the backs of my thighs.

"I was finally liberated from these judgments that I had surrounding my body, which I realized had existed since I was ... a teenager. Since being a mum, I've embraced it all. The lumps and the bumps and the stretch marks... it's a map of my journey of bringing my babies into the world."
