A new Monte Carlo model is proposed for radiative corrections to Bhabhascattering by extending QEDPS developed for multi-photon emission in muon pairproduction in $e^+e^-$ annihilation. This is the QED version of the model knownas parton shower in QCD. The main difference between muon pair production andBhabha scattering is that the latter cross section shows the singularity of$1/t^2$. A shower algorithm is constructed on the radiator formalism modifiedin a suitable form for this singularity. Some results of the model arepresented and compared with $O(\alpha)$ corrections.Comment: 12 pages, LaTeX, 4 figures available on request KEK-CP-009,KEK Preprint 93-14
