"This could be the very first time where they break with tradition and don't have a traditional fruitcake", said McGrady, who was the Royal Chef with Queen Elizabeth from 1982 to 1993, and with Princess Diana and Prince William and Harry from 1993 to 1997. "It has been wonderful getting to know Meghan and to see how happy she and Harry are together". Additionally, there is precedent for this, as the pair performed these ceremonial duties earlier this year at Pippa Middleton's wedding. As it turns out, it's not an indication of any bad blood between them.
Numerous key roles for the wedding have yet to be announced, but The Times speculates that Prince William is a likely choice for best man, and Markle's stylist and friend Jessica Mulroney "is expected to play an important part beyond helping the bride choose her dress".
Meghan Markle has a lot of famous friends, so there has been plenty of speculation about whether people like Serena Williams or any of Meghan's Suits co-stars will be in the wedding party - or if Meghan's future sister-in-law Kate Middleton will be a bridesmaid.
This is because there is technically no such thing as a best man at a royal wedding.
Marlene Koenig, a British and European royalty expert, explained to Town and Country: "The best man or best men are officially called supporters".
Well, following a long United Kingdom tradition, there's an official one (usually a fruitcake) and another personally picked by the prince (usually a childhood favorite.) When Kate Middleton married Prince William, she had will a multi-tiered fruit cake made by Leicestershire baker Fiona Cairns, featuring edible flowers - an English rose, a Scottish thistle, a Welsh daffodil and an Irish shamrock - and a chocolate biscuit cake by McVitie's made to a secret Royal Family recipe. "William will probably be Harry's supporter".
The newly engaged couple Prince Harry and Meghan Markle stepped out today for their first royal outing in Nottingham, and quite naturally, all eyes were on Markle's outfit.
But considering Meghan and Harry are all about slightly deviating from the norm and causing a bit of good-natured royal ruckus, we're pretty pleased the couple are choosing to buck tradition in the cake-realm, too.
