Pippa Middleton, the youngest sister of Duchess of Cambridge, married hedge fund manager James Matthews in Englefield, England today.
The Royal family - Catherine Middleton along with Prince William, Duke of Cambridge and Prince Harry - was also present to attend the ceremony.
The 33-year-old arrived with her father in an open-top vintage car.
The 45-minute ceremony took place just a few miles away from the Middleton estate, where the marquee reception was held.
Catherine Middleton was spotted wearing a light pink dress with a deep V-neck and matching fascinator, with her two children, reports CNN.
Other guests, who attended the ceremony, included Tennis stalwart Roger Federer and his wife, Mirka.
