  We investigate the regularizing effect of certain perturbations by noise in
singular interacting particle systems under the mean field scaling. In
particular, we show that the addition of a suitably irregular path can
regularise these dynamics and we recover the McKean--Vlasov limit under very
broad assumptions on the interaction kernel; only requiring it to be controlled
in a possibly distributional Besov space. In the particle system we include two
sources of randomness, a common noise path $Z$ which regularises the dynamics
and a family of idiosyncratic noises, which we only assume to converge in mean
field scaling to a representative noise in the McKean--Vlasov equation.
