It's not often we get to see the power couples of entertainment put on a PDA.
The majority of them keep their private life exactly that. So, when they hit up the red carpet, not only do we get the chance to see some of the world's best dressers come together in a moment of sartorial harmony but we also get to ogle the chemistry between couples we rarely get to see side by side.
And the Cannes Film Festival, which kicked off yesterday, has always provided excellent red carpet fodder when it comes to couples having a moment. From Charles and Diana to Ryan Gosling and Sandra Bullock (yes, really), take a look back at the most breathtaking and charming red carpet appearances of the last few decades.
