Kesuba saying she is a virgin when she has already told the groom it isn't true

 Igros Moshe (OC IV #118) Writing the ketubah for a woman who had been sexually active and she has already informed the groom, there is no need to tell the rabbi performing the ceremony since the groom will sign the ketubah and he has agreed to the kesubah saying that she is a virgin even though it isn’t so. Since she is not deceiving him and he in fact wants to obligate himself according to the amount for a virgin and thus is no different than any additions voluntarily added to the kesubah.
