The data of $X(3872)\\rightarrow \\pi^+\\pi^-\\pi^0 J/\\psi$ suggest that X(3872) may be a high-spin charmonium-like of $2^{-+}$. In terms of the light front quark model (LFQM) we calculate the rates of the radiative decays $X(3872)\\rightarrow J/\\psi(\\psi')\\gamma$ supposing X(3872) to be a $2^{-+}$ charmonium. Within this framework, our theoretical prediction on $\\mathcal{BR}(X(3872)\\rightarrow\\psi(1S)\\gamma)$ is at order of $10^{-3}$ which is slightly lower than the Babar's data but close to the Belle's.
