We present the first frequency-domain model for inspiral, merger and ringdown of the GW signal from precessing binary-black-hole systems that also includes multipoles beyond the leading-order quadrupole. Our model, {\\tt PhenomPv3HM}, is a combination of the higher-multipole non-precessing model {\\tt PhenomHM} and the spin-precessing model {\\tt PhenomPv3} that includes two-spin precession via a dynamical rotation of the GW multipoles.
