The GPDs of $\\bar{u}$ and $\\bar{d}$ quarks can be expressed as the convolution of the light cone wave functions which are obtained from the baryon-meson fluctuation model in terms of the $|q\\bar{q}B\\rangle$ Fock states. We present the numerical results for $H^{\\bar{u}/P}(x,\\xi,\\Delta^2)$, $H^{\\bar{d}/P}(x,\\xi,\\Delta^2)$, $E^{\\bar{u}/P}(x,\\xi,\\Delta^2)$ and $E^{\\bar{d}/P}(x,\\xi,\\Delta^2)$.
