Meghan and Harry are set to marry in May 2018。
Meghan Markle has only recently announced her engagement。 But already it seems that her wedding plans are forging ahead - with claims she‘ll be joined by two very special guests at the centre of the ceremony。
The reason for this is simple: Catherine Middleton was not of royal blood, and what applies to her will also apply in the case of Meghan Markle.
But Sarah Ferguson was never Princess Sarah and Sophie Rhys-Jones - the wife of Prince Edward - is not Princess Sophie.
Meanwhile， Prince William is also expected to take the role of best man at the event， next spring， but his duty will be deemed as being a ‘supporter’。
The pair， who are the Queen‘s great-grandchildren， will be centre stage at St George’s Chapel， Windsor， as the American actress weds their uncle， Prince Harry。
Officially, we can forget about Princess Kate and we can forget about Princess Meg.

Royal blood made them princesses in their own right.
A spokesperson for the palace said： “The wedding will be a family event。 You can expect the family to be involved。
That means that she cannot call herself Princess Meghan.
She married producer Trevor Engelson in September 2011 - after dating him since 2004 - but the union collapsed in May 2013。
Jason Knauf said Prince Harry, 33, and Ms Markle were "leading the planning process for all aspects of the wedding" and were working through ideas on how members of the public could "feel part of the celebrations".
It is reported that the royal siblings have been confirmed as both pageboy and bridesmaid respectively。
Ms Markle, 36, a Protestant, will be baptised into the Church of England and confirmed before the wedding.
Not that this is the first time Meghan has walked down the aisle， of course。
A spokesman for the prince said the pair would make sure the wedding "reflects who they are as a couple".
According to reports， the brunette beauty， 36， will have both Prince George and Princess Charlotte follow her down the aisle。
It will come seven years after Prince Harry held the same role at William‘s wedding to Kate Middleton。
The arcane rules mean that Meghan will be compelled to follow the example of her future sister-in-law.
Prince Harry and Meghan Markle will marry at St George's Chapel, Windsor Castle, in May, Kensington Palace says.
But the Queen could also make both Kate and Meghan princesses in their own right - but such are the rigid traditions surrounding this issue that Britain's first Princess Meghan is likely to be some time away.
