TV viewers leapt to the defence of Prince George after Wimbledon commentator Andrew Castle got himself into a muddle.
The young prince attended Sunday's final between Novak Djokovic and Nick Kyrgios with his parents, the Duke and Duchess of Cambridge. During a lull in the on-court action, the BBC tennis pundit appeared to confuse George with his younger sibling Louis.
Referencing scenes from the Queen's Platinum Jubilee celebrations, Mr Castle commented that George had been caught "just slightly misbehaving". But royal watchers at home were quick to rush to Twitter to set the record straight.
One tweeted: "Andrew Castle getting it wrong. George wasn't misbehaving, it was Louis."
A second remarked: "Just said the same in our house - if you're gonna spout stuff at least get the right Prince!"
George joined his parents in the royal box on Sunday in what Kate described as a "treat" for the eight-year-old. The duchess, who is patron of the All England Club, wore a navy blue skirt and matching top with white polka dots by designer Alessandra Rich.
The royals first greeted a group of military personnel who were working as stewards at the championships, the Express reported. Kate quizzed them about their duties and asked how many championships they had worked at Wimbledon.
She then explained to George what the stewards do, saying: "They look after everybody to make sure the crowds are safe and happy, doing the right thing, in the right seats, making sure the grounds are safe."
When asked about George coming to Wimbledon, she said: "Is this your first time? It is, isn't it?" to which he replied: "Yes". When asked why Charlotte was not there, she said: "It's George's treat today."
George was also asked who he was going to support and appeared too shy to answer so Prince William looked at him and whispered: "Djokovic."
"We'll see how long it lasts. He'll support the winner," added the Duke. William then spoke to them about Kyrgios' powerful serve and Djokovic's experience in playing grand slam finals. He added: "I think it's going to be an electrifying spectacle."
