We've been eagerly reading about the entire David Petraeus controversy. Just a few weeks ago, we were bowled over by the sensational news of Bilawal Bhutto, the son of Pakistani President, Asif Ali Zardari, being in the thick of a love affair with the foreign minister's daughter, Hina Rabbani Khar. The President was infuriated after apparently finding the two in a 'compromising position' at his residence and is dead against his 24-year-old son marrying a woman who's 11 years older than him and the mother of two daughters. Needless to say, the affair is scandalous and has captured the entire nation's imagination but it is by no means something we've never seen before. 

From media revealed hand-written letters between the love birds to incessant tabloid reporting on the matter, this is a political love affair that will go down in history. Naturally, it got us thinking about all the others there have been too. So without further ado, here are five of the world's greatest (and more current) love affairs.
