  It is now known that the shadow is not only the property of a black hole, it
can also be cast by other compact objects like naked singularities. However,
there exist some novel features of the shadow of the naked singularities which
are elaborately discussed in some recent articles. In the earlier literature,
it is also shown that a naked singularity may admit negative precession of
bound timelike orbits which cannot be seen in Schwarzschild and Kerr black hole
spacetimes. This distinguishable behavior of timelike bound orbit in the
presence of the naked singularity along with the novel features of the shadow
may be useful to distinguish between a black hole and a naked singularity
observationally. However, in this paper, it is shown that deformed Kerr
spacetime can allow negative precession of bound timelike orbits when the
central singularity of that spacetime is naked. We also show that negative
precession and shadow both can exist simultaneously in deformed Kerr naked
singularity spacetime. Therefore, any observational evidence of negative
precession of bound orbits, along with the central shadow may indicate the
presence of a deformed Kerr naked singularity.
