Chris Hemsworth has become a first-time dad. The "The Avengers" star's wife Elsa Pataky gave birth to their first child on Friday, May 11 afternoon in London, a source confirms to Us Weekly.

Details surrounding the baby are scarce but Hola.com reported that it was a baby girl named India Rose. Both mother and child are fine and they have returned home.

Hemsworth married Spanish actress Pataky during the 2010 Christmas holiday after dating for a few months. They announced the pregnancy in January. "Chris and I are ecstatic, very happy and excited," Pataky said at that time. "Since it's our first child we don't care if it's a boy or girl, our only wish is that it's healthy."

Pataky and her big belly still walked the red carpet at the U.K. premiere of "The Avengers" last month.
