Prince William joined his wife Kate Middleton, who is a keen tennis fan and patron of the All England Lawn Tennis Club, to see Australia's Ashleigh Barty beat Czech Republic's Karolína Plíšková, clinching her second Grand Slam title.
While the royal couple thoroughly enjoyed the nail-biting game, after it finished they were left scrambling to delete a tweet they had sent - because of a small typo!
This afternoon the royal couple posted: "Well done to @wimbledon and the staff on continuing to make the Championships such a special event."
But eagle-eyed followers would have noticed that an almost identical tweet was fired off before this and quickly deleted because they had crucially misspelt Wimbledon as 'Wimbldedon'.
The small blunder came after the couple sent their congratulations to champion Ashleigh on her "incredible" final. "What an incredible match and performance by both athletes! Congratulations @ashbarty on being crowned #Wimbledon champion," they tweeted.
