We obtain predictions for B(s) → e+e−γ and B(s) → μ+μ−γ decays. All the contributions containing long-distance QCD effects are calculated in the framework of relativistic quark model. The contributions of the light vector-meson resonances related to the virtual photon emission from valence quarks of the B-meson are included. The highest branching ratios for the radiative leptonic B-decays are B(B̄0s → e+e−γ) = 18.8×10−9 and B(B0s → μ+μ−γ) = 12.2×10−9. We also give the distribution of the foward-backward asymmetry.
