Every time a celebrity couple decides to make it official to the public, it becomes big news, but not quite as big as when they break up.

Robert Pattinson Moves On From Kristen Stewart?

One of the latest couples to be talked about non-stop is Kristen Stewart and Robert Pattinson. Even though they broke up a good while ago, they're still being rumored to be getting back together and possibly having an open relationship. What made these two a huge deal was that they starred in one of the biggest blockbusters of all time where they played a couple on-screen. Therefore, them dating in real life made a massive impact on the public. But their breakup became even more of a shock since it looks like they won't have the same ending that their on-screen characters had.

Another common breakup was between Katy Perry and John Mayer. This is mainly because they were both popular singers who appeared to blend well, but unfortunately, things didn't work out in the way their fans had probably hoped.
