  Deep r' and i' images obtained with GMOS on Gemini South are used to probe
the bright stellar content in the outer regions of NGC 5253 and ESO269-G058.
Red giant branch (RGB) stars are traced out to a distance of 8 kpc along the
major axis of NGC 5253, and 6 kpc in ESO269-G058. The outer regions of both
galaxies are metal-poor; RGB stars located between projected major axis
distances of 2 and 4 kpc in NGC 5253 have [Fe/H] ~ -1, whereas RGB stars in the
corresponding portion of ESO269-G058 have [Fe/H] ~ -1.8. Stars with
metallicities that differ from the mean by more than a few tenths of a dex make
only a modest contribution to the stellar content in the outer regions of both
galaxies. A population of bright asymptotic giant branch (AGB) stars is seen in
both galaxies. Roughly 1 - 10% of the stellar mass of NGC 5253 may have formed
during the past few hundred million years, and it is suggested that the
progenitors of the two recent SN Ia in this galaxy may have formed at this
time. It is argued that the current episodes of star formation in NGC 5253 and
ESO269-G058 may have been triggered up to ~ 1 Gyr in the past. Finally, a
distance modulus is computed for each galaxy based on the brightness of the
RGB-tip, and the results are 27.48 +/- 0.14 for NGC 5253, and 27.93 +/- 0.18
for ESO269-G058.
