 Similarly, actress Dame Judi Dench should be addressed as "Dame Judi", not "Dame Dench" or "Ms Dench".Wives of knights, however, are entitled to the honorific pre-nominal "Lady" before their husband's surname.Thus Sir Paul McCartney's ex-wife was formally styled "Lady McCartney" (rather than "Lady Paul McCartney" or "Lady Heather McCartney").
