  More than 100 microlensing events have been detected during the last ~4
years, most of them towards the Galactic Bulge. Since the line of sight towards
the Bulge passes through the disk and the Bulge itself, the known stars towards
the Bulge play a dominant role as gravitational lenses. If these stars have
planets around them, then the signature of the planets can be seen as sharp,
extra peaks on the microlensing light curves. Frequent, continuous monitoring
of the on-going microlensing events thus provides a powerful new method to
search for planets around lensing stars.
  Here I first review the background on stars acting as gravitational lenses. I
then review the theoretical work on possible observational features due to
planets, and the probability of detecting the planets through microlensing. I
then discuss the status/strategy/results of the observational programs
currently active in this field.
