Using the Vector Meson Dominance model, the amplitude for the chain process B_{s} --> \\phi\\psi --> \\phi\\gamma --> \\gamma\\gamma is estimated and it is found to be at most 4 % of the corresponding amplitude from the O_7 type LD contribution. The intermediate amplitude for the process B_{s} --> \\phi\\gamma is compared with the corresponding one obtained by a different approach based on the interaction of the virtual charm quark loop with soft gluons \\cite{Ruckl}. Both amplitudes are found to agree within 10 %.
