  We study timelike and conventional entanglement entropy as potential probes
of black hole singularities via the AdS/CFT correspondence. Using an
analytically tractable example, we find characteristic behavior of holographic
timelike entanglement entropy when the geometry involves a curvature
singularity. We also observe interesting phenomena that, in some particular
setups, holographic timelike and conventional entanglement entropy are
determined from multiple complex saddle points, which fall outside the
assumptions of the Lewkowycz-Maldacena type argument.
