‘Jersey Shore’ Cast’s Shocking Makeovers Must Be Seen to Be Believed (PHOTOS)

jwowwDid you happen to see Jersey Shore star Deena Nicole Cortese at the VMAs last week? The 25-year-old showed off her body in a tight black mini dress and wowed everyone with her new, uh, face. Seems like Deena's had some subtle work done -- fillers? botox? brow lift? -- but whatever she's doing, it's working, because girl looked good ... even if she is a little unrecognizable.

Deena's not the only one who's undergone a transformation ever since busting onto the MTV scene a few years ago. In fact, every cast member has dramatically changed their appearance since the cameras started rolling in 2009. Let's take a trip down gym, tan, memory lane and check out how the J.S. boys and girls have morphed over the last three years.

Who do you think has changed the most?
