We discuss singlet extensions of the MSSM withZ4Rsymmetry. We show that holomorphic zeros can avoid a potentially large coefficient of the term linear in the singlet. The emerging model has both an effectiveμterm and a supersymmetric mass term for the singletμNwhich are controlled by the gravitino mass. Theμterm turns out to be suppressed againstμNby about one or two orders of magnitude. We argue that this class of models might provide us with a solution to the little hierarchy problem of the MSSM.
