Chris Hemsworth & Elsa Pataky Spark Debate After Playfully Pushing Son's Face Into Birthday Cake

The Hemsworth household loves celebrating birthdays head on! Chris Hemsworth and wife Elsa Pataky's twin sons, Tristan and Sasha, turned 9 this week and the couple added a playful surprise to the festivities. In a family Instagram photo shared to Chris' account, Elsa is pictured pushing one of the boy's face into his cake, as big sister India, 10, assists with a smile. Though the whole crew sported big grins in the snap, some fans were concerned that the prank may not have been as fun as intended.
