 One of the most frequently asked questions to couples is always, “How did you two meet?”

In One Day, Anne Hathaway and Jim Sturgess play strangers who, after one memorable day together on July 15, 1988, begin a lifelong friendship. For the next two decades, the film checks in on the two of them every July 15—their “anniversary”— and explores their tumultuous relationship.

To celebrate the film’s premiere, Celebuzz has compiled a list of celebrity duos with serendipitous hook-up stories. Regardless if married or separated, these stars sure have one heck of a story to tell! It can take one day to meet your soul mate, and a lifetime to realize it!
