As the future King of England and the groom in the wedding of the decade, it would be safe to assume that everyone knows what Prince William looks like, but a company in China still managed to confuse him with little brother, Prince Harry, Breaking Celebrity News has learned.

Guandong Enterprises from China have released a mug to commemorate the royal wedding with Prince Harry smiling cheekily at bride-to-be Kate Middleton -- and Will's name painted underneath.

With his mop of red hair and boyish freckles, Harry doesn't look anything like William so it's hard to imagine how the mix-up happened... unless there's something the pair aren't telling us!

The site calls the April 29 wedding: “The Fairytale Romantic Union Of All the Centuries” and invites shoppers to: "Please be our guests to own this esteemed limited edition heirloom to celebrate your work associates, friends, family and loved ones on April 29th."
