We consider supersymmetric extensions of the standard model with two pairs of Higgs doublets. We study the possibility that {ital CP} violation is generated spontaneously in the scalar sector via vacuum expectation values (VEV`s) of the Higgs fields. Using a simple geometrical interpretation of the minimum conditions we prove that the minimum of the tree-level scalar potential for these models is always real. We show that complex VEV`s can appear once radiative corrections and/or explicit {ital soft} {ital CP}-violating terms are added to the effective potential.
