\begin{abstract}
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 lightcurves.
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.
