Ryan Reynolds and Scarlett Johansson have been engaged less than a week and are already talking about starting a family. Reynolds, 31, says he does want a child with Johansson as he feels it is their “destiny.”

“I do want a child at some point,” he says. “I feel like I need to fulfill the genetic paradigm, the destiny of it all.”

The couple announced their engagement Monday. Johansson, 23, showed off her engagement ring the next day.
