Un-inviting Someone to Wedding… need advice!!!!

Hi! I’m looking for some advice. We are about 3 months out from my wedding … 2 weeks out from sending invites. There are 2 people that are on the side of my FH that we sent save the dates to but as of recently have continuously gone behind our backs saying really rude and disrespectful things about me and our relationship. They are known to a lot of people in our friend group for a lot of gossip and causing a lot of drama. I am the complete opposite, I hate drama, I hate knowing or having people talk behind my back, especially people that I have always been kind, respectful and caring towards. I love doing things for other people but for once I am being selfish when it comes to our wedding, I want our day to be happy and drama free and I want it to be filled with people who genuinely care about us and show us the same love and respect that we show towards others. I really hate confrontation too but I feel like I need to uninvite these two guests who have really gone out of their way to start rumors, drama etc not just about us, but others invited to our wedding. How do I go about this? Please be kind… this is really the last thing I want to do but again, I just don’t want people there who have been so disrespectful towards us recently.
