Wills and Kate dropped by for the men's Wimbledon finale to cheer on their dear friend Roger Federer.
The mum-of-two was an absolute vision in a Catherine Walker & Co design. The white floral dress was the perfect match for the summery day, showing off the future queen's stunning physique and signature pins.
As she entered the royal box, Kate completed her look with soft curls, a green and purple bow-shaped Wimbledon brooch and gold earrings by British designer Cassandra Goad.
The 35-year-old was accompanied by her leading man, who looked exceptionally dapper in navy trousers and a very on-point sky blue line blazer.
The proud parents, who will tour Germany and Poland this week, were the picture of romance, affectionately touching each other as they watched Roger win his historic eighth Wimbledon title, beating Croatian Marin Cilic 6-3, 6-1, 6-4.
Also in the stands was the entire Middleton clan, who all seemed rather pleased with results.
Kate recently showed off her funny side, admitting to the BBC, “Every time Wimbledon is on I am there thinking, ‘Yes, I could do the same’ and get out the racket. Sadly, never the same results!”
She also dished that her mum, Carole Middleton had quite the thing for the tennis champ, Roger.
“Roger [Federer] is my mother’s heartthrob. I don’t think she will mind me saying that! I think he probably knows that too,” she mused.
