  Planets orbiting very close to their host stars have been found, some of them
on the verge of tidal disruption. The ellipsoidal shape of these planets can
significantly differ from a sphere, which modifies the transit light curves.
Here we present an easy method for taking the effect of the tidal bulge into
account in the transit photometric observations. We show that the differences
in the light curve are greater than previously thought. When detectable, these
differences provide us an estimation of the fluid Love number, which is
invaluable information on the internal structure of close-in planets. We also
derive a simple analytical expression to correct the bulk density of these
bodies, that can be 20% smaller than current estimates obtained assuming a
spherical radius.
