Kate Middleton impresses Roger Federer with tennis skills at Wimbledon; WATCH

WIMBLEDON 2023 is still some weeks away but the green turf at the iconic tennis venue saw a unique friendly match being played recently and on either side of the nets were two celebrated named -- former champion Roger Federer who has the most number of Wimbledon crowns (eight) and Kate Middleton, the princess of Wales.

A video of their match went viral on the Internet and it showed the two individuals engaging in a game of tennis in whites.

After Federer, who called it quits last year, asked, "Shall we play some tennis?", Middleton showed off her strong forehand shot and returned all of her male opponent's shots with ease.

The 20-time Grand Slam champion was polite to ask Middleton who should start and the latter invited him to begin the game.

She also earned Federer's accolade after scoring a point by landing a shot at the line.

"I think it was on the line, amazing!" the Swiss told her.

Wimbledon also uploaded the video on their Instagram account with the caption, "I think it was on the line! Consider us impressed..."

Middleton frequently visits the Royal Box at the Wimbledon as a royal patron of the All England Lawn Tennis Club, a CNN report said.

During the session, Middleton, 41, also sought advice from Federer on improving her serve and transitioned into the roles of a ball boy and girl.

Federer also appreciated the training session, saying, "This is proper practice, I'm impressed."
