Adelaide actor Teresa Palmer has welcomed her fourth child, a baby girl called Prairie Moon.

Palmer, 35, shared the good news on social media today, after giving birth at her Adelaide Hills home earlier this week.

“Introducing our daughter, Prairie Moon Palmer, who was born just as the sun rose on Tuesday morning, 17th August, surrounded by her siblings who are absolutely enamoured with her,” she wrote on Instagram.

“A little magic moon for our family.”

The Hollywood actor and her filmmaker husband Mark Webber are already parents to sons Bodhi Rain, 7, and Forest Sage, 4, and daughter, Poet Lake, 2.

Webber also has a teenage son, Isaac, from a previous relationship.

Ride Like a Girl star Palmer, who gave birth at home through the Flinders Midwifery Group Practice, shared a series of adorable photos of her children meeting their new sister.

The family arrived back in Palmer’s hometown, in early July, after spending some time in their other home, Los Angeles.

Palmer wrapped filming on her latest horror flick, The Twin, in Estonia, in May.

Prior to that, she was shooting Foxtel sci-fi series A Discovery of Witches in Wales.

A budding entrepreneur, Adelaide-born Palmer launched a series of low- impact “living retreats” around SA earlier this year, and she’s also co-founder of Lovewell, a range of 100 per cent plant-based nutritional supplements.
