Prince Harry and Meghan Markle have invited two very important women to their wedding

And it's making everyone emotional.

Prince Harry and Meghan Markle's wedding is fast-approaching, with the couple set to wed in a matter of days at St. George's Chapel, Windsor Castle.

The wedding will see friends and family come from far and wide to celebrate the nuptials, from Meghan's former Suits co-stars to Prince Harry's army chums. And in terms of A-list attendees, the event is said to be star-studded, giving Prince William and Kate Middleton's 2011 ceremony a run for its money.

We're talking the Beckhams, Elton John and the Spice Girls to name just a few confirmed guests.

Even they can't compete with two very important attendees however, with Prince Harry and Meghan Markle inviting two very special women to the nuptials.

The VIP guests in question? Princess Diana's sisters, Lady Sarah McCorquodale and Lady Jane Fellowes.

It was announced earlier this month that Prince Harry's aunts would be playing a role in the wedding, with a source explaining how the 33-year-old prince remained close with the two women.

'Harry has always kept in touch with the Spencers and they have all received invitations,' explained the source. 'He gets on well with his aunts and uncle and they have met Meghan.'

Earlier this month Kensington Palace released a statement detailing how the two sisters would be involved in the wedding.

'In addition to having the support of The Queen, his father The Prince of Wales, and his brother Prince William as Best Man, Prince Harry is also keen to involve his mother's family in the wedding,' the statement read.

'All three siblings of Diana, Princess of Wales will be in attendance and Lady Jane Fellowes will give the reading. Prince Harry and Ms. Markle both feel honoured that Lady Jane will be representing her family and helping to celebrate the memory of the late Princess on the wedding day.'

Not long to wait now till the big day.
