How does she do it? After wowing the crowds at Trooping the Colour, Kate is surprise guest at wedding of her 'royal matchmaker'

The man credited with saving Prince William and Kate's romance got a surprise guest at his own wedding today - the Duchess of Cambridge.

Just hours after she proudly watched her husband take part in his first Trooping the Colour, Kate joined guests at the wedding of close friend Sam Waley-Cohen, who married party organiser Bella Balin today.

The jump-jockey was branded the royal matchmaker after apparently helping Kate and Wills rekindle their romance after their brief split in March 2007 - a claim which Mr Waley-Cohen has modestly denied since.

The pair chatted with friends, villagers and wedding guests outside St Michael and All Angels Church in Lambourn, near Hungerford in Berkshire, before the ceremony began.

Wearing a fitted monochrome spot-pattern dress - but still sporting the black hat she wore for the Royal ceremony at Buckingham Palace earlier in the day - the Duchess was accompanied by her younger sister Pippa Middleton, who donned a lime-green coat over a dark dress and a black hat. 

According to onlookers, the future Queen drove herself to the wedding and had apparently changed into a new outfit since her appearance on the balcony of Buckingham Palace, where she wore a fitted white coat.

Royalist and Lambourn resident Carol Morgan joined a small crowd of well wishers outside the church.
