First on the list is Ryan Gosling and Rachel McAdams. The Notebook co-stars made fans swoon during the Nicholas Sparks movie adaptation in 2004, even winning the Best Kiss award at the MTV Movie Awards the following year. Their chemistry was so intense that when the couple reenacted their kiss as the awards show, their fellow celebrities in the audience sported looks of visible shock as they cheered them on.

Despite initially not getting along on set, the couple began dating in 2005, and were together until 2007. They briefly broke up and reunited in 2008, but again, they broke up. McAdams is currently single, and Gosling is dating actress Eva Mendes, though the relationship has been reported to be on the rocks, giving fans hope that McAdams and Gosling will once again rekindle their romance.

Another couple fans were sad to see split was Adam Brody and Rachel Bilson. The OC co-stars dated for three years during the show's run, but ended their relationship in 2006. Both appear to have moved on permanently -- Brody married Gossip Girl star Leighton Meester in February, and Bilson has been with actor Hayden Christensen since 2007.
