  We review the potential of the LHC to detect a very light CP-odd Higgs boson
of the NMSSM, $a_1$, through its direct production in association with a
bottom-quark pair at large tan$\beta$. We also review the LHC discovery
potential of the two lightest CP-even Higgs states, decaying into two lighter
Higgs states or into the lightest CP-odd Higgs state and the $Z$ gauge boson.
