The supermodel has so much clout in the Cotswolds, where she lives with Kills fiance JAMIE HINCE, that she has been allowed to effectively shut Little Faringdon and Southrop, in Oxfordsire.
Guests, including her 18 bridesmaids, have been sent a special permit to enable them to access the wedding venues.
A source told The Sun: “Kate hopes closing the towns will ensure there's no unwanted intrusion on her big day.
“Guests will have to flash permits to security who will be lining the roads leading into the town. Locals have also received permits so they can come and go as they please.”
Ms Moss planned to wed at the church in the garden at her mansion in Little Faringdon but it was too small for her 400 guests so the couple will marry a church in the village of Southrop.
