Celebrity couples are often a bit of a mixed bag, right? It's always cool to see two famous people hook up and get cosy with one another, and when they're a good match then the pairing can often be better than the sum of its parts. However, in the vast majority of cases, they don't seem to last very long. Maybe it's because the media can't give them any privacy, or because their personalities clash, but often they only seem to go out for a week or so before breaking up with other.

As a result of this, there are plenty of celebrities who have dated each other in the past, whom we've forgotten were ever an item. In fact, it can actually be quite jarring to see pictures of them with their former flame, if you're already used to their current partner.
