What should a gal do if her fiancee might see her in a video?

I have a bunch of wild and crazy friends all part of a bohemian bunch who are getting along in years, hence are cooling down. So there is this super hot party gal whos been there done that and now wants to settle down in calmer latitudes. As in most such cases the guys are straight arrow dependable type that have probably spent their youth face buried in books. Come time to marry these hot gals somehow choose the bland bread earners to settle down. This gal has an unique situation since in the past she has appeared in many private videos, copies of which are not impossible to obtain, but not in video stores. She brought the topic up many times and her fiancee seems totally turned off to the idea of watching such movies leave alone see her permorm her acrobatics in one. Is there a tactful way of disclosing this not so subtle matter to this future hubby so as to not have to suture the relationship in future?
