CUORE is a ton-scale underground bolometric array of 988 $TeO_{2}$ crystals built with the aim of searching for the lepton flavor violation via the neutrinoless double beta decay of ${}^{130}Te$. A report on both neutrinoless and two-neutrino double beta decay search to the first $0^{+}$ excited state of ${}^{130}Xe$ will be presented. A coincidence analysis of the energy released in different bolometers by de-excitation gammas produced in the final state helps reducing the background.
