Royal fans everywhere have the chance to get their hands on a portion of the royal couple's eight tier wedding cake in an auction held by Chiswick Auction House.

The cake is set to go on sale on September 27, with a guide price set at £800. However, it is thought the slice of dessert will end up selling for a lot more as a previous piece of cake raked in an impressive £8,000.

Whoever bids the highest will be the proud owner of the slice of cake, which will be placed in a special cream and gold commemorative tin - the same one given to the guests at the wedding back in April 2011.

The tin has a printed card, which reads: "With the best wishes from the TRH The Prince of Wales and The Duchess of Cornwall in celebration of the wedding of TRH the Duke and Duchess of Cambridge."

It comes after Duchess of Cambridge's hairdresser Richard Ward revealed that Catherine was very "calm" on her wedding day.

He said: "I have some incredible memories of that day. When she walked back into Buckingham Palace and her hair was all still in place, I cannot tell you the relief we all felt! I've seen brides far more nervous that Catherine! She was fantastic - she kept us calm, not the other way round!

"I wanted to show Kate the back of her hair [getting ready at Clarence House for the evening party] and I was struggling to walk with this 500-year-old mirror. He just said, 'Let me give you a hand.' And I said, 'No, no, honestly.' But he took one end and I've got the other and we're shuffling along with this mirror - he's great, he really is. It was the most incredible experience and I'll never forget it."
