Abstract: In this poster we present the results of our analyses of three early massivestars in IC 1613, whose spectra have been observed with VIMOS and analyzed withCMFGEN and FASTWIND. One of the targets resulted a possible LBV and the othertwo are Of stars with unexpectedly strong winds. The Of stars seem to bestrongly contaminated by CNO products. Our preliminary results may represent achallenge for the theory of stellar atmospheres, but they still have to beconfirmed by the analysis of more objects and a more complete coverage of theparameter space.
