The 35-year-old Israeli actress posed with her hands on her stomach between her husband Yaron Varsano and their two daughters in a photo posted Monday.
Gadot representatives also confirmed the news to CNN.
Her pregnancy announcement came just hours after she presented the prize for best foreign language photo at the 78th annual Golden Globe Awards – an event that took place pretty much this year because of the pandemic.
Gadot and Varsano were married in 2008. Their first daughter, Alma, was born in 2011 and their second child, Maya, in 2017.
“It’s cheesy, but I feel like Wonder Woman when I give birth. When you give birth, you feel like a god. Like, ‘Oh my God, I made this.’
“The best thing is to become a mother and give life.”
Godot first made her Hollywood film debut in the “Fast and Furious” franchise in 2009.
But she rose to fame as warrior Diana Prince, first as a cameo in 2016’s “Batman v. Superman: Dawn of Justice” and then in “Wonder Woman” the following year.
Wonder Woman 1984 was released in 2020 and the third installment of the DC Comics franchise has been announced.
