Kate Middleton's parents watched Wimbledon 2018 together.

On the third day of the tennis tournament, Michael and Carole Middleton were spotted at the event. According to Lauren O'Callaghan, a journalist for Express, Middleton's mom always attends the tournament every year with her stylish look.

During Carole's latest sighting, she wore a white crisp dress with a broderie-anglaise design. Her getup is a few inches above her knees which showed off her tan legs.

The Duchess of Cambridge's mom paired her dress with nude and grey wedges. She accessorized with dark sunglasses and a leather handbag. On the other hand, Middleton's dad opted for a dark navy suit.

It remains unknown if Middleton will attend the event as she is still on maternity leave. Initially, royal fans were hoping to see her with her sister-in-law, Meghan Markle, at the tournament. The Duchess of Sussex will reportedly make several appearances at Wimbledon to cheer on her good friend, Serena Williams.

The Duchess of Cambridge is a self-confessed tennis fan. In fact, prior to joining the royal family, she used to spend hours lining up just to get a ticket for Wimbledon.

"Being able to go into Wimbledon and be part of an amazing atmosphere is special," Middleton said. "It inspires young people including myself. Every time Wimbledon is on I am thinking 'Yes, I could do the same' and get out the racket. Sadly, not the same results."

Middleton also revealed that she was banned from Wimbledon in 2013. According to Prince William's wife, she begged her doctor to allow her to watch the finals, but her request was turned down. So, she wrote a letter to the winner.

"I was very heavily pregnant. I wrote to him [Andy Murray] afterwards saying sorry for not being there," Middleton said.

In related news, Andre Agassi, an American retired professional tennis player and the former world No. 1, opened up about his encounter with Middleton. The athlete has nothing but praises to the royal mom of three.

"She was a complete doll," Agassi described Middleton to Hello! at Wimbledon last week. "I really thought she was incredibly pleasant. She was lovely. We didn't chat a whole lot but she was lovely. I will not say anything else, because I don't know what offends people here or not!"
