  In the framework of the Hard Thermal Loop effective theory, we calculate the
two-loop contributions to hard lepton pair production in a quark-gluon plasma.
We show that the result is free of any infrared and collinear singularity. We
also recover the known fact that perturbation theory leads to integrable
singularities at the location of the threshold for $q\bar{q}\to\gamma^*$. It
appears that the process calculated here significantly enhances the rate of low
mass hard dileptons.
