Ryan Gosling and Rachel McAdams: 2005-2007 and 2008
According to Ryan, Rachel McAdams was also one of "the greatest girlfriends of all time." She and Ryan got together in mid-2005 after meeting on the set of their 2004 weep-fest The Notebook, and they dated for two years before splitting in mid-2007. But that wasn't tne end of their love story: They rekindled their romance in the summer of 2008, only to call it quits again that November.
After their first break, Ryan told GQ (via People), "God bless The Notebook. It introduced me to one of the great loves of my life. But people do Rachel and me a disservice by assuming we were anything like the people in that movie. Rachel and my love story is a hell of a lot more romantic than that."
