The Duchess of Cambridge has turned 40 this weekend.
The milestone birthday is likely to be a private family affair marked at the Cambridges’ home in Norfolk.
The pair officially announced their engagement in November 2010, with William saying in his engagement interview: “When I first met Kate I knew there was something very special about her.”
The couple were married at Westminster Abbey on April 29 2011 in a ceremony watched around the world.
Kate has toured the world with William and in 2016 made her first official solo overseas trip to the Netherlands.
