15 Most Shocking Celebrity Breakups

2/15 Rachel McAdams and Ryan Gosling

Lovers on screen and off, fans and media alike went berserk when the dynamic duo playing the beloved Notebook couple started dating in real life. Reportedly, the pair did NOT get along when the first met on set. In fact, Gosling wanted to kick McAdams off the film because their vibes were just not, well…vibin. However, that all seemed to change as the couple started dating shortly after the film wrapped in 2004. They dated for three glorious years and broke up in 2007. They briefly re-sparked the flame in 2008, but quickly decided to call it quits for good.
