Chris Hemsworth and his wife Elsa Pataky are expecting their second child together.
A representative for the Thor star confirmed the happy news, according to E! Online.
Hemsworth, 30, and Pataky, 37, started dating in early 2010 and married that December. Pataky's pregnancy comes over a year after the couple welcomed their first child, daughter India Rose Hemsworth.
The actor has previously spoken about how fatherhood has changed him "for the better".
He told E! News: "It puts things into perspective."
The star opened up to Parade magazine last month about being a father, saying: "I think [parenthood] brings out the child in all of us.
"That's what's so beautiful. It reminds you of the fascination you had with things and how you can spend hours just being with someone. It's amazing."
