  Based on data from the ongoing OGLE Galaxy Variability Survey (OGLE GVS) we
have verified observed properties of stars detected by the near-infrared VVV
survey in a direction near the Galactic plane at longitude l~-27 deg and
recently tentatively classified as classical Cepheids belonging to a, hence
claimed, dwarf galaxy at a distance of about 90 kpc from the Galactic Center.
Three of four stars are detected in the OGLE GVS I-band images. We show that
two of the objects are not variable at all and the third one with a period of
5.695 d and a nearly sinusoidal light curve of an amplitude of 0.5 mag cannot
be a classical Cepheid and is very likely a spotted object. These results
together with a very unusual shape of the Ks-band light curve of the fourth
star indicate that very likely none of them is a Cepheid and, thus, there is no
evidence for a background dwarf galaxy. Our observations show that a great care
must be taken when classifying objects by their low-amplitude
close-to-sinusoidal near-infrared light curves, especially with a small number
of measurements. We also provide a sample of high-amplitude spotted stars with
periods of a few days that can mimick pulsations and even eclipses.
