Chris Hemsworth revealed why his wife Elsa Pataky hasn’t taken his last name. Chris and Elsa met in 2010 and after dating for a few months, they got married later the same year. Today, they share three children: India Rose (7), and twin sons Tristan and Sasha (6). The Thor actor recently spoke on the Australian Kyle and Jackie O radio show, where he revealed that a complication with their passports kept her from taking the actor’s sir name.
