Monaco Prince in Nightclub Brawl

He’s the earl of knuckle sandwiches. Monaco’s Prince Pierre Casiraghi wound up in the hospital after the 24-year-old royal was laid out in a nightclub brawl Saturday in Manhattan’s meatpacking district. Casiraghi, the grandson of Grace Kelly, reportedly got into a fight with Adam Hock, a former nightclub owner, who was arraigned Sunday on charges of assaulting the prince and three friends. The prince’s lawyer said his client did not “instigate anything” and was released from the hospital after treatment. Hock, however, has another story, telling the New York Post that the prince and pals were “being completely obnoxious.”
