A mystery man resembling Prince Harry appeared in Kate Middleton's Christmas show trailer, sparking speculation on social media.

Talking to BBC Radio 4's Today show in December 2017, the Duke of Sussex revealed that the couple’s first Christmas together at Sandringham had involved spending a lot of time with Prince George, now 11, and Princess Charlotte, now nine. Prince Louis was not yet born at the time.

Kate Middleton has been busy promoting her Christmas special, Royal Carols: Together at Christmas, which airs in England on ITV tonight, and apparently there's a, uh, Prince Harry lookalike in the trailer. Ahem: And here's the trailer for your viewing pleasure/confusion:

Prince Harry — what are you doing here? A Prince Harry look-alike was spotted at Kate Middleton’s Christmas carol service that took place on Dec. 6 and will be televised on Christmas Eve. The doppelgänger appears at the 35-second mark in the trailer for the annual celebration hosted by Harry’s sister-in-law.

Prince William and Prince Harry may not agree on much these days, but when they were kids, the sons of King Charles and Princess Diana both enjoyed this Christmas dessert, a former chef at Kensington Palace revealed.

Prince Harry wrote that he once received a "cold-blooded" Christmas present from Princess Margaret but said he wished he had had more time to get to know her. Writing his memoir Spare, the Duke of Sussex wrote that said "cold-blooded" Christmas present was a biro wrapped in a tiny rubber fish.
