  We present recent results of two interesting classes of supersymmetric
two-loop contributions to (g-2)_mu. Two-loop diagrams involving either a closed
sfermion loop or a closed chargino/neutralino loop can amount to 5*10^{-10},
which is almost one standard deviation of the current experimental uncertainty.
We discuss the dependence of these two classes on the unknown supersymmetric
parameters and their impact on the supersymmetric prediction of (g-2)_mu.
