Jersey Shore Drama!

On Thursday night's "Jersey Shore," Sammi Giancola punched her on-again-off-again boyfriend Ronnie Ortiz-Magro in the jaw after she found out he had reconciled with her mortal enemy and housemate ìJwowwî Farley.

Over the years, Jersey Shore has featured guy-on-guy violence, guy-on-girl violence, girl-on-girl violence and now, finally, girl-on-guy violence. (Via TV Squad)
