Robert Irvine boasted numerous places about having participated in the baking of Lady Diana and Prince Charles' wedding cake. For instance, here. Also, in the introduction to his HarperCollins book entitled Mission: Cook!

Times writer Ben Montgomery corresponded with the baker who actually was responsible for baking the cake, Dave Avery (pictured with the cake, above). Here's an article about Avery's experience.

Irvine made the claim to several St. Petersburg locals that, in addition to having been part of the baking team, he still had the top tier of the cake in his freezer.

Avery responded to Montgomery this morning via e-mail:

"Thank you for your very interesting e-mail. Robert Irvine may have been a trainee student at the Royal Naval Cookery School whilst I was making the Royal Wedding Cake. He most certainly was not involved with me in making or baking the cake. I did make two identical wedding cakes, just in case of accidents. The second cake I cut up and distributed to all the trainees in the Naval Cookery School. So, there is a possibility that he may have a piece of that one. It would only be about an inch square finger of cake. Maybe you could ask him questions that only I would know the answer to! e.g. Where was I when it was announced to the public that I was making the cake? The answer: HMS Drake in
Plymouth. Or who did I ask to draw the blueprint to take to Lady Diana for her approval? The answer: Barry Dunkley. Looks like Robert Irvine has a very successful career in the USA. Good luck to him--hope he hasn't built his career on lies. Time will always find you out! Regards."
