  A half-BPS circular Wilson loop in $\mathcal{N}=4$ $SU(N)$ supersymmetric
Yang-Mills theory in an arbitrary representation is described by a Gaussian
matrix model with a particular insertion. The additional entanglement entropy
of a spherical region in the presence of such a loop was recently computed by
Lewkowycz and Maldacena using exact matrix model results. In this note we
utilize the supergravity solutions that are dual to such Wilson loops in a
representation with order $N^2$ boxes to calculate this entropy
holographically. Employing the matrix model results of Gomis, Matsuura, Okuda
and Trancanelli we express this holographic entanglement entropy in a form that
can be compared with the calculation of Lewkowycz and Maldacena. We find
complete agreement between the matrix model and holographic calculations.
