  We show that the entanglement entropy of $D=4$ linearized gravitons across a
sphere recently computed by Benedetti and Casini coincides with that obtained
using the Kaluza-Klein tower of traceless transverse massive spin-2 fields on
$S^1\times AdS_3$. The mass of the constant mode on $S^1$ saturates the
Brietenholer-Freedman bound in $AdS_3$. This condition also ensures that the
entanglement entropy of higher spins determined from partition functions on the
hyperbolic cylinder coincides with their recent conjecture. Starting from the
action of the 2-form on $S^1\times AdS_5$ and fixing gauge, we evaluate the
entanglement entropy across a sphere as well as the dimensions of the
corresponding twist operator. We demonstrate that the conformal dimensions of
the corresponding twist operator agrees with that obtained using the
expectation value of the stress tensor on the replica cone. For conformal
$p$-forms in even dimensions it obeys the expected relations with the
coefficients determining the $3$-point function of the stress tensor of these
fields.
