Summer after summer, we've watched them party, tan, and throw-down on the Jersey Shore. And now, America's favorite roommates head to the shore one last time. Fresh out of rehab, Mike "The Situation" is navigating the party-world of clubs and nightlife while maintaining his sobriety and mending relationships with his former roommates. MVP is finally back! And with Mike's newfound maturity, he may even decide to make it official with his on-and-off girl Paula. Deena is in love for the first time and turns to hardcore partying while struggling with being away from her boyfriend. Jenni and Roger's relationship continues to grow and get pushed to its limits. Speaking of rocky relationships, Sammi and Ron are back together. In the bromance department, Vinny & Pauly are still going strong. And all the roommates rally around Snooki as she goes through her pregnancy as only she can! It's a Jersey Shore Baby on the way and all the girls throw Snooki a shower. Seaside is home and to this Jersey Shore family, there's no better place to bring up baby. But even with impending adulthood, you can't tame this crew. The more things change, the more they stay the same.
