Kate's mum, Carole Middleton, isn't the only super fan of the Wimbledon champion. On Wednesday an article about Roger written by Anna Wintour was published on Tennis.com. The fashion icon penned, "Fan is quite an understatement. I have flown across the world for his tournaments; I've endured agony when he's been a set down and ecstasy when he's stormed back; I have even missed more than the occasional fashion show—all for the privilege of witnessing Roger play what is surely the greatest tennis of all time."

Anna added, "It's no secret that he’s appeared in Vogue about as often as Karlie Kloss. Everyone calls themselves Roger Federer fans. I consider myself a groupie."
