Kate and William Join Mexican Wave at Wimbledon

William and Kate entered fully into the Olympic spirit today, participating in a Mexican wave while seated in the Royal Box at Wimbledon, as they watched British player Andy Murray cruise to victory in the men's singles quarter finals against Nicolas Almagro of Spain today.

Kate was seen crying after Murray was defeated in the Wimbledon final by Federer last month.

Kate was wearing a £515 Stella McCartney knee-length dress, last worn to an opening at the National Portrait Gallery.

The Mexican waves lapped around the bleachers between games.
