  Recent results of two-loop contributions to the muon (g-2) in the Standard
Model and its supersymmetric extension are presented. In the SM the EW
contributions are fixed according to the Higgs boson mass measured at LHC. In
the MSSM we present the recent result of fermion/sfermion two-loop
contributions. The fermion/sfermion contributions are logarithmically enhanced
for large sfermion masses and can yield the largest corrections compared to all
previously known MSSM two-loop contributions. Numerical results in scenarios
which are compatible with LHC data are also presented. We find up to 15\%
(30\%) corrections for sfermion masses in the 20 TeV (1000 TeV) range.
