Tennis aficionado Kate Middleton, the Duchess of Cambridge, has revealed that she was banned from attending the Wimbledon final back in 2013, which saw Andy Murray take the men’s singles title for the first time

Speaking to BBC presenter Sue Barker for a documentary about tennis, the Duchess told of how she “begged” her doctor to let her attend the showdown between Murray and Novak Djokovic when she eight months pregnant with her first child, Prince George — and revealed that she has since apologized to Murray for missing the big match.

“Wimbledon […] was very much part of my growing up,” she said. ‘Roger [Federer] is my mother’s heartthrob. I don’t think she will mind me saying that! I think he probably knows that too.”

According to Kate, her father, Michael, committed a faux pas at the tennis tournament when he confused Tim Henman with American player Pete Sampras.
