  The complementarity between the quark and lepton mixing matrices is shown to
provide a robust prediction for the neutrino mixing angle $\theta_{13}^{PMNS}$.
We obtain this prediction by first showing that the matrix $V_M$, product of
the CKM and PMNS mixing matrices, may have a zero (1,3) entry which is favored
by experimental data. Hence models with bimaximal or tribimaximal forms of the
correlation matrix $V_M$ are quite possible. Any theoretical model with a
vanishing (1,3) entry of $V_M$ that is in agreement with quark data, solar, and
atmospheric mixing angle leads to $\theta_{13}^{PMNS}=(9{^{+1}_{-2}})^\circ$.
This value is consistent with the present 90% CL experimental upper limit.
