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.

According to reports, the brunette beauty, 36, will have both Prince George and Princess Charlotte follow her down the aisle.

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.

It is reported that the royal siblings have been confirmed as both pageboy and bridesmaid respectively.

A spokesperson for the palace said: "The wedding will be a family event. You can expect the family to be involved.

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'.

It will come seven years after Prince Harry held the same role at William's wedding to Kate Middleton.

Not that this is the first time Meghan has walked down the aisle, of course.

She married producer Trevor Engelson in September 2011 - after dating him since 2004 - but the union collapsed in May 2013.

Meghan and Harry are set to marry in May 2018.
