Weddings are such an important event in so many people's lives that being asked to be part of their ceremony is a huge honor. On the other hand, not even being invited to someone's wedding can feel like a huge snub or a slap in the face.
However, the couple getting married are entitled to invite — or not invite! — whoever they want to their special day, even if their decisions ruffle some feathers. The same, of course, goes for actors, who often give everyone else an insight into their relationships with their costars based on who gets an invitation.
