"I'm telling you - his superpower is parenting." Robert Downey Jr. is impressed with his The Avengers co-star Chris Hemsworth's multi-tasking abilities as a dad. The Thor hunk and his wife Elsa Pataky are parents to nearly one-year-old twins Tristan and Sasha, and two-year-old daughter India Rose. Downey Jr. also welcomed his third child last year (14) - daughter Avri Roel, who was born in November.
