All of the guests had RSVP'd except for one couple, friends of the groom's family. The grooms mother called them to check and they said that Yes they were coming, and bringing their 23 year old daughter...? The invite said "Mr. & Mrs. Smith." We are right at the limit for guests, and we are having a very small guest list with immediate family and a few friends. I don't want to come off like bridezilla, but I don't really want some random girl coming that we don't even know and be responsible to pay for her. I'm just annoyed... advice?
