Ryan Reynolds and Blake Lively - Age gap: 11 years
Ryan Reynolds previously revealed that he fell for his wife Blake Lively when he was actually on a date with someone else. The actor and the actress had agreed to go on a double date with other people, about a year after filming Green Lantern together.
"That was the most awkward date for the respective parties because we were just fireworks coming across," Ryan told SiriusXM. "It was weird at first, but we were buddies for a long time. I think it's the best way to have a relationship, to start as friends."
Blake and Ryan married in September 2012, and in December 2014 they welcomed their daughter James, followed by daughter Inez in 2016.
