Will Smith and Jada Pinkett Smith: 15 Years
Will and Jada met on the set of Fresh Prince of Bel-Air in 1990, when Jada tried out for the role of Will's onscreen girlfriend. Deemed too short for the role, she didn't end up getting the part. The two kept in touch, however, and got together in 1995. They married in 1997. Jada is the stepmother of Will's son Trey, whom he had in a previous marriage. Together, the couple has two children, Jaden and Willow.
