Any wedding with Prince William as best man and Zara Phillips as a bridesmaid is unlikely to remain low-key for long.

So reports at the weekend that the Queen’s eldest grandson, Peter Phillips, and his Canadian bride, Autumn Kelly, below, had decided to wed in the tiny Crathie Kirk, near Balmoral Castle, surprised many. Now, a friend of the couple has set the record straight.

“They’re actually getting married in St George’s Chapel in Windsor Castle,” says my source at a party for Glenmorangie whisky. “It can seat up to 800 people, so it’ll be quite a big do. Autumn’s certainly not thinking low key when it comes to the dress, either.

She’s having it made by the Fulham-based designer Sassi Holford, who is creating something completely original which will be called The Autumn.”

Buckingham Palace declined to comment, saying only: “He is a private individual and we don’t speak on his behalf.” (via The Telegraph)
