We investigate the interaction between a heavy quark-antiquark pair in color octet configuration in a gluon plasma. We calculate nonperturbatively the effective thermal potential for hybrid states with static QQ octet and an adjoint gluonic source. We compare the results for two different gluonic sources, which lead to completely different potentials in the confined phase. We find that they show identical thermal potentials to large distances, and interpret this potential as the interaction potential between the static Q and the Q in a color octet configuration. We present results for the potential in gluon plasma for moderately high temperatures \ensuremath\lesssim2Tc. The implications of our result are discussed.
