An anomalous emission component at energies of a few GeV and located towardsthe inner Galaxy is present in the Fermi-LAT data. It is known as the Fermi-LATGeV excess. Using almost 8 years of data we reanalyze the characteristics ofthis excess with SkyFACT, a novel tool that combines image reconstruction withtemplate fitting techniques. We find that an emission profile that tracesstellar mass in the boxy and nuclear bulge provides the best description of theexcess emission, providing strong circumstantial evidence that the excess isdue to a stellar source population in the Galactic bulge. We find a luminosityto stellar mass ratio of $(2.1\pm 0.2)\times 10^{27}\mathrm{\,erg\,s^{-1}\,M_\odot^{-1}}$ for the boxy bulge, and of $(1.4\pm0.6)\times 10^{27}\mathrm{\,erg\,s^{-1}\,M_\odot^{-1}}$ for the nuclear bulge.Stellar mass related templates are preferred over conventional DM profiles withhigh statistical significance.
