  The discovery of planets around massive stars is important for understanding
how planet formation and evolution is conditioned by different stellar
environments. However, current planetary search surveys have failed to detect
planets around massive evolved stars. This lack of planets might be a
consequence of the specifities of planet formation around such objects.
Alternatively, the detection of planets around evolved massive stars might be
hindered by the increasing stellar jitter as the stars evolve. In this project
we target planets around evolved stars in open clusters, most of them with
masses above 2 M$_\odot$. We present the cases of three objects where long term
(i.e. years) and high amplitude RV signals of probably stellar origin are
mimicking the presence of planets.
