  The azimuthal correlation of D mesons with charged particles in pp collisions
at $\sqrt{s}$ = 7 TeV was measured using the ALICE detector at LHC. This
measurement allows us to gain insight into heavy-flavour production processes
and parton shower. The results are compared with the measurement performed in
p-Pb collisions. The yield of charged particles in the near-side correlation
peak and the peak width measured in the two collision systems are compatible,
within the uncertainties, and described by Monte Carlo simulations.
