The availability at the LHC of the largest collision energy in pp collisions
allows a significant advance in the measurement of J/$\psi$ production as function
of event multiplicity. The interesting relative increase observed with data
at the LHC at $\sqrt{s}=7$ TeV and at RHIC at $\sqrt{s}=200$ GeV is studied now
at unprecedented multiplicities at $\sqrt{s}=13$ TeV.
The new measurement, performed at midrapidity in the dielectron channel with
ALICE and facilitated by triggering on high-multiplicity events, allows the
comparison to J/$\psi$ production in p-Pb collisions at similar multiplicities.
The results are also discussed in comparison to predictions from available theoretical models and to data at lower energies.
