A study investigating a possible jet shape dependence on the charged event multiplicity is conducted on collision samples generated by Monte-Carlo (MC) event generators PYTHIA and HIJING++. We calculated the integral jet shape and found a significant modification caused by multiple-parton interactions. By interchanging and enabling different model ingredients in the simulations and analyzing the results in several $p_T$ windows and event multiplicity classes, we have found a characteristic jet size measure that is independent of the chosen tunes, settings and jet reconstruction algorithms.
