Exciton polaron states in C60 molecular are theoretically studied in the tight-binding approach supplemented by the extended Hubbard interaction. The binding energies of the lowest singlet and triplet excitons depend sensitively upon the electron correlation. Then the exciton polaron is formed due to the electron-lattice coupling. Relevent experiments in photo-luminescence spectrum of Cso can be explained qualitatively by the present model with moderate interaction strength .
