It is well-known \citemtbh that \em all black hole solutions of General Relativity are of Petrov-type D. It may thus be expected that the spacetime of \em physically realizable spherical gravitational collapse is also of Petrov-type D. We show that a radially homothetic spacetime, \em ie, a spherically symmetric spacetime with hyper-surface orthogonal, radial, homothetic Killing vector, is of Petrov-type D. As has been argued in \citeprl1, it is a spacetime of \em physically realizable spherical collapse.
