Now that Jersey Shore is over for good, it's time to take a moment to reflect on how much the cast has changed. Every single cast member has undergone some sort of transformation since we first met them, but who's made the biggest 180?

We've run down the changes as we see them. Look it over, and then let us know who you think wins the title of Most Changed.

Deena Nicole: From single drunk mess to taken, skinnier, and ... OK, still sometimes a drunk mess.

JWOWW: JWOWW's had a physical transformation, but the biggest change is her transition from party girl to devoted fiancee.

Sammi and Ronnie: We could talk about these two separately, but let's be honest: The real change here is in the SamRon relationship, which went from dysfunctional disaster to amazingly adorable.

Snooki: The original meatball went from borderline pathetic party animal to smart businesswoman and responsible new mom (and that's not even touching on her weight loss!).

The Situation: Well, he's sober now, which is a pretty freaking monumental change right there.

Pauly D: From small-time DJ to opening for Britney Spears.

Vinny: From quiet mamma's boy to outspoken activist with a new hipster style.

Who do you think changed the most? Let us know in our poll!

Snooki & JWOWW Season 2 premieres on Tuesday, January 8 at 10 p.m. ET/PT on MTV.
