Welcome Wedding Note What Is The Best Way To Tell Someone That They Are Not Welcome At Your Wedding?

What is the best way to tell someone that they are not welcome at your wedding? - welcome wedding note

I mean, the person is a bit arrogant. My friend and I have said very clearly that there is a private ceremony, mostly family. This person has asked his assistant photographer at our wedding. I need a pretty strong way, but you know that is not welcome at our wedding. Oh yes .... my friend is not supported and close friends were several years ago. Thank you in advance for your answers!
