There's a Hollywood saying: Celebrity couples never last. While some managed to prove us wrong - look at Will and Jada Pinkett Smith - most of the time, their romantic sparks usually fizzle out after a year or two together.

On Tuesday (16.03.2010), it was reported that Oscar-winning actress, Kate Winslet, and her director husband of six years, Sam Mendes, have mutually decided to go their separate ways. According to their lawyers, "the split is entirely amicable and is by mutual agreement". But then they always say that, don't they?

And as another one bites the dust, MSN Entertainment takes a look at some of the celebrity couples who went their separate ways and those who are about to.
