The Princess of Wales is well-known for her love of sports and exercise and keenly supports a number of important sporting organisations, such as the Rugby Football Union and the All England Lawn Tennis and Croquet Club.
As their patron, Kate is a frequent visitor to Wimbledon and is often seen clapping and cheering the athletes on.
One tennis star who she is particularly close with is Roger Federer, 41. The Swiss tennis player is known to be good friends with the Princess and even attended her sister Pippa's wedding to James Matthews in 2017.
