Triple Parton Scattering with the CMS experiment.

The recent observation of three $J/\Psi$ production from the same event from the CMS Collaboration raised large interest in the Triple Parton Scattering (TPS) component of the pp interaction. In this contribution a description of the measurement will be provided, together with the results interpretation in terms of Single, Double and Triple Parton Scattering. Also, ongoing promising studies on the possibilities of observing TPS in events containing open charm mesons ($i.e.$, $J/\Psi$ + J/\Psi + $D^{*}$) will be discussed.
