  If the $J^P$ of $\Theta_5^+$ and $\Xi_5^{--}$ pentaquarks is really found to
be ${1\over 2}^+$ by future experiments, they will be accompanied by
$J^P={3\over 2}^+$ partners in some models. It is reasonable to expect that
these $J^P={3\over 2}^+$ states will also be discovered in the near future with
the current intensive experimental and theoretical efforts. We estimate
$J^P={3/2}^+$ pentaquark magnetic moments using different models.
