Prince William & Kate: Foundation Polo Challenge Pair!
The event will bring together polo elite from around the world to raise money for The American Friends of the Foundation of Prince William and Prince Harry.
William is expected to play in the match on Team Royal Salute. The event started off with a lunch prepared by chef Giada De Laurentiis before the main game.
Later in the evening, the Duke and Duchess of Cambridge, both 29, will attend the BAFTA dinner held at the Belasco Theatre.
FYI: Kate is wearing a Jenny Packham dress.
