For many people, the last place they would like an ex is at their wedding. Even those who have managed to stay friendly with those with whom they were previously in a relationship would probably not invite many of their exs to watch them wander down the aisle with someone else. But the royal family does things a little differently and sometimes their marriages are like parades of old girlfriends and old boyfriends.

So, why would members of the royal family feel the need to invite exes to their weddings? The reason is that their social circles form a very united club and it is therefore important to remain courteous and invite all members of this exclusive group, whether they are ex or not.

It is here that the old flames of all, from Prince Charles to Kate Middleton, were invited to this royal affairs.
