The Point Break star and her actor/director husband Mark Webber welcomed Forest Sage in the early hours of Monday (12Dec16) in her native Australia, and she has since introduced fans to the couple's new addition.

Alongside a photo of the new family-of-four, she wrote, "Our sweet littlest love is here. Forest Sage Palmer was born... in Adelaide on 12/12 at 12:18 p.m... Our hearts are so full and blessed."

The couple wed in 2013 and also shares son Bodhi Rain, who was born in February, 2014. Mark has another boy, eight-year-old Isaac Love, from his relationship with actress Frankie Shaw.

Teresa announced her second pregnancy in May (16).

Little Forest's birth occurred hours before the actress' new movie, Hacksaw Ridge, scored three nominations for the 2017 Golden Globes. The World War Two drama is shortlisted for Best Motion Picture - Drama, Best Director - Motion Picture for Mel Gibson, and Best Performance by an Actor in a Motion Picture - Drama for Teresa's onscreen love interest, Andrew Garfield.
