Taking account of the constraint from radiative two body decays l_i→ l_jγ, we investigate the Lepton Flavor Violation decays B^0_q→l̅_̅l̅l_k in the framework of the minimal extension of the Standard Model with one neutral singlet scalar. The couplings C_eμ, C_eτ and C_μτ between the different generation leptons and scalar S^0 are constrained by the current bounds of l_i→ l_jγ. The numerical results show that the theoretical prediction of B^0_q→l̅_̅l̅l_k strongly depend on the couplings C_qb
