We analyse the CP asymmetry for B_{s} -->\gamma\gamma in the two Higgsdoublet model with tree level flavor changing currents (model III) and threeHiggs doublet model with O_2 symmetry in the Higgs sector, including O_{7} typelong distance effects. Further, we study the dependencies of the branchingratio Br(B_{s} --> \gamma\gamma)$ and the ratio of CP-even and CP-odd amplitudesquares, R=|A^{+}|^2/|A^{-}|^2, on the CP parameter sin \theta. We found that,there is a weak CP asymmetry, at the order of 10^{-4}. Besides, the branchingratio Br(B_{s} --> \gamma\gamma), and also R ratio, is not sensitive to the CPparameter for |\frac{\bar{\xi}^{U}_{N,tt}}{\bar{\xi}^{D}_{N,bb}}|<1.Comment: 17 pages, 11 figure
