SARAH MICHELLE GELLAR AND FREDDIE PRINZE JR. – 18 YEARS
The 1997 thriller film I Know What You Did Last Summer is known to be one of the classics that any American film buff has to watch at least once. The stars of that movie Sarah Michelle Gellar and Freddie Prince Jr. met on the set of the movie, and while their chemistry on the screen was obvious, it was still a pleasant surprise when they began dating in 2000 because they had only been friends till then.
The couple got engaged in 2001 and tied the knot in a ceremony held in Mexico the following year. The actor couple has continued working on several projects together, including movies like Scooby-Doo and Happily Never After. Their 20 plus yearlong partnership has obviously bought them financial success, but more importantly, a happy family that includes two loving children.
