The bride and groom were spotted leaving the church in a sports car similar to the Aston Martin Volante that Prince William took Kate for a spin in following their wedding at Westminster Abbey.
It was at a party at Mr Waley-Cohen's family's 17th Century mansion in Oxfordshire in June 2007 - after they split in March 2007 - that William and Kate were seen in deep conversation sparking rumours that a reunion could be on the cards.
Just weeks later the pair were spotted aboard a yacht on a private island in the Seychelles.
And the rest, as they say, is history!
Who do you think won the fashion face-off this time? We're loving Kate's look...
