The complementarity between the quark and lepton mixing matrices is shown to provide a robust prediction for the neutrino mixing angle θ13PMNS. We obtain this prediction by first showing that the matrix VM, 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 VM are quite possible. Any theoretical model with a vanishing (1,3) entry of VM that is in agreement with quark data, solar, and atmospheric mixing angle leads to θ13PMNS=(9+1-2)^∘. This value is consistent with the present 90% CL experimental upper limit.
