Jennifer Garner and Ben Affleck
This Hollywood pairing seemed destined to last, making it all the more devastating that it didn't. Jennifer and Ben first met in 2000 during the filming of "Pearl Harbor" but didn't fall in love until 2002 while working on "Daredevil."
They got engaged in 2005, after ending their previous relationships, and tied the knot a few months later. The couple welcomed their first child shortly after their wedding and had three children during their relationship. However, they announced their separation in 2015.
