2012 is going to be a big year for Chris Hemsworth.

In addition to reprising his role as Thor in The Avengers, the 28-year-old Aussie will welcome a child with wife Elsa Pataky this spring, Hemsworth's rep confirms to Us Weekly.

The actors, who wed in December 2010, are "delighted and very excited" to become first-time parents.  Spanish actress Pataky, 35, tells ¡Hola!: "Having the person that you love by your side and starting a family with them is the best thing that can happen to you in this life. You can't ask for more."

What does Hemsworth love most about his wife, who recently starred opposite Vin Diesel and Paul Walker in Fast Five?

"She's always smiling," Hemsworth told Us in April. "She's a lot of fun to be around."
