MTV's "Jersey Shore" will premiere its sixth season on Thursday. The reality show debut will mark the beginning of the end for the series, as this season will be its very last. Similar to its past, the latest and last installment of the show is still promising to deliver audiences fights, drama and hook-ups. However, it also will feature two scenarios that viewers aren't used to seeing: a six months pregnant Snooki and Mike "The Situation" Sorrentino battling a prescription meds addiction.
