Prince William might not be Prince Harry's best man

They're the best of friends so why can't Wills be Harry's ultimate wingman on his big day?

We'll never forget the moment Prince Harry told his nervous big brother, "Just wait til you see her", as his bride-to-be Kate Middleton made her way up the hallowed aisle of Westminster Abbey during the last royal wedding in 2011 (which you can relive in the player above).

But now we might not get to see similar scenes play out at Prince Harry and Meghan Markle's ceremony in May next year.

As it turns out, Prince William may not even get the role of best man.

Don't panic just yet, the two haven't had a falling out!

This is because royal weddings traditionally don’t have "best men," but the groom can appoint a number of "supporters."

Prince William actually broke protocol when he named Prince Harry as his best man.

"The best man or best men are officially called supporters," British and European royalty expert Marlene Koenig told Town & Country.

"William will probably be Harry's supporter.”

However, a source told Us Weekly that Harry already asked if William would stand beside him on the big day.

“Harry has several close guy friends, but there’s no way he would ask anyone but William to take on the top job,” the insider revealed.

In the past, Harry and William have opened up about their unbreakable bond which was made even stronger after the death of their mother Princess Diana in 1997.

"We have been brought closer because of the circumstances as well, that's the thing. You know, we are uniquely bonded because of what we've been through," William explained in April this year.

It’s also thought Harry’s niece, Princess Charlotte, and nephew, Prince George, will have important roles to play in the wedding as bridesmaid and page boy.

Since the announcement last week, more details surrounding the royal wedding have been released.

A date has been set for May 2018 and the Queen has approved St George’s Chapel at Windsor Castle as the location for the ceremony.
