I wouldn't waste the energy. If she is family then it will eventually get back to her (you could "let it slip" around other family members to make sure).
That way you 1) Look like the bigger person because you didn't rub it in her face, and 2) Still get the pleasure of knowing that she knows so still sort of rubbing it in without actually rubbing it in.
Does that make sense?
