Recent observations and theories suggest that extreme horizontal branch (EHB) stars and their progeny should be the cause of the UV excess that many elliptical galaxies show in their spectra. Since the Galactic bulge is the closest representation of an old, metal-rich spheroid in which we are able to study the EHB scenario in detail, we obtained spectra of bulge EHB star candidates and we confirm their status as hot evolved stars. It is the first time that such stars are unambiguously observed in the Galactic bulge.
