In this paper we continue our investigation of gauge/gravity duality in
 11d pp-wave using the BMN matrix theory. We study a spherical antimembrane
 in the eleven dimensional pp wave. In this background, a single antimembrane
 breaks all the supersymmetries because its dipole is misaligned with the
 background flux. Using the BMN matrix theory we compute the one-loop
 potential for the antimembrane. Then we put the antimembrane in the field
 produced by a source spherical membrane and compute the
 velocity-dependent part of the interaction between them on both the
 supergravity side and the BMN matrix theory side. Despite the
 aforementioned nonsupersymmetry of the antimembrane, it is
 found that the results on the two sides completely agree.
