Carole Middleton watches her tennis crush Roger Federer at Wimbledon

By Sharnaz Shahid

Carole Middleton appeared to be in great spirits as she and her husband Michael stepped out at Wimbledon on Thursday (July 6). Dressed appropriately in all-white, the Duchess of Cambridge's mother looked radiant as she sat in the Royal Box on Centre Court alongside Roger Federer's father Robert. With her tresses swept into a ponytail, Carole made sure she protected herself from the sunshine with a pair of designer shades whilst toting her belongings in a nude Chanel handbag.

The Middleton family have been regular attendees at this year's Wimbledon, with both Pippa, 33, and Kate, 35, having all paid a visit earlier this week. On Wednesday, newlywed Pippa looked sensational in a blush-hued midi dress from fashion-forward label Self-Portrait. The semi-sheer lace number, worth $467, featured cape sleeves, waist-cinching ribbon detailing and a contrasting white collar. Pippa has not long arrived back from her honeymoon, which saw her and her new husband James Matthews jet around French Polynesia and Australia. The Duchess' little sister looked fabulous as she cheered on Andy Murray to victory alongside her brother James.

Why was Roger Federer at Pippa Middleton and James Matthews' wedding?

It's hardly surprising that the Middleton's were seated next to tennis champion Roger's father. The 18 Grand Slam winner and his wife Mirka were amoung the guests who attended Pippa's wedding in May. Elsewhere, in a documentary broadcast earlier this week, Kate revealed that her mother has quite the crush on the sporting ace. She told presenter Sue Barker: "I have watched Wimbledon that was very much part of my growing up. Roger [Federer] is my mother's heartthrob. I don’t think she will mind me saying that! I think he probably knows that too."
