Kate Middleton and Andy Murray are doing their part to make Wimbledon 2020 a special occasion.

Of course, the famed annual tennis tournament was cancelled this year amid the COVID-19 pandemic. But some of the event's biggest stars are still taking part in community activities during the would-have-been Wimbledon schedule (June 29 - July 12).

On Friday, the Royal Family's social media pages shared a special call that Kate placed to a group of youth tennis players at Bond Primary School in South London. The Duchess is a regular attendee of Wimbledon, and is patron of All England Lawn Tennis and Croquet Club (AELTC). The children appeared starstruck to chat with the Duchess, but she had prepared another surprise guest from the sporting world: British tennis icon Andy Murray.

Kate, who wore a tennis-print dress during the call, led into the big reveal:

"I've got a very important person here that's going to come and join us, that would love to meet you guys and might be able to share some tennis tips as well with you. I'll give you a few clues and see if you can guess who this special guest might be. So he is a he. He plays tennis for Great Britain. He's a two-time Olympic champion. He's a former World Number One. Can you possibly guess who this might be?"

The 33-year-old tennis star then appeared on the call and chatted with Kate, the children, and their coaches. Fittingly, Murray, a two-time Wimbledon Men's Singles champion, joined the call ahead of what would've been Finals weekend at Wimbledon 2020. He spoke about his early interest in tennis, how old he was when he began playing, and life in lockdown.

Andy Murray was Men's Singles champion at Wimbledon in 2013 and 2016.

On Wimbledon's launch day, Kate and the AELTC shared a video that reflected on resilience and the importance of Wimbledon 2020's cancellation amid health concerns. They also encouraged fans and enthusiasts of the sport to get creative and re-create Wimbledon from home.

Despite the cancellation, the young tennis players at Bond Primary School will no doubt remember their Wimbledon 2020 week. The full 10-minute video call is included below via the Royal Family!
