The other day, I read about Frank Sinatra putting out a hit on Howard Stern after Stern criticized his family members. One person claimed that a man who resembled Stern was in fact murdered accidentally in a case of mistaken identity.

This reminded me of the time James Caan supposedly used his contacts in the mafia to rough up Joe Pesci.

Are there any other cases of celebrities using mob connections to settle scores?

I invoke my right under the 5th amendment of the United States constitution and decline to answer the question.
