The 30-year-old actress - who already has two-year-old Bodhi with her husband Mark Webber - has taken to social media to announce her "sweet littlest love", Forest Sage Palmer, was born on Monday (12.12.16) in Adelaide, Australia, and the pair feel "blessed" with their new arrival.

The 'Point Break' star shared a picture of her, with her partner - who also has eight-year-old son Isaac from a previous relationship - Bodhi and the new addition to their family on her Instagram account.

She captioned the heart-warming photograph: "Our sweet littlest love is here Forest Sage Palmer was born yesterday in Adelaide on 12/12 at 12:18pm weighing 8lb 4oz and 20 inches long! Our hearts are so full and blessed, he is perfect! Picture by our girl@gemma_peanut (sic)."

Teresa - who married her actor-and-director partner in 2013 - also shared the same photograph on Twitter.

She tweeted: "Forest Sage Palmer has arrived earth side Our hearts are full and blessed. 12/12 at 12:18pm in Adelaide. 8lb 4oz (sic)."

Meanwhile, Teresa has revealed prior to giving birth she has been craving the scent of an air detox spray - which claims to disinfect and purify the air - and ordered 10 bottles of the product because she loves to cover her pillows in the smell.

Speaking previously the Australian star said: "This is a weird one because it has nothing to do with food! I've been obsessed with smelling Dr Shulze's Air Detox spray!

"I literally have ordered a full box of the spray (10 bottles!). I like to spray all of my pillows with it before bed and just engulf myself in the scent as I fall asleep. It's a mixture of eucalyptus, lime and lemon! Mark thinks it's hilarious and I had the exact same obsession with the same smell first pregnancy! I'm convinced it'll help me throughout labour (sic)."
