A k-ellipse is a plane curve consisting of all points whose distances from k fixed foci sum to a constant. This talk concerns the singularities and genus of the Zariski closure of k-ellipses in the complex projective plane. At the end, we will discuss the canonical images of 3-ellipses in the moduli space of genus 3 curves.
