Deena Nicole Cortese, Paul "Pauly D" Delvecchio, Jenni "JWOWW" Farley, Vinny Guadagnino, Ronnie Ortiz-Magro, Nicole "Snooki" Polizzi and Mike "The Situation" Sorrentino will all take part in the special.
The only cast member not returning for some GTL? Sammi "Sweetheart" Giancola, who sources say opted to sit out of the special due to her ex-boyfriend Ronnie. A source told E! News, "She's happy in her current relationship and didn't want to be disrespectful of that."
Despite his recent legal battle (pleading guilty in his tax fraud case), The Situation will be back in action. After arriving a day later than the rest of his cast members, The Situation was greeted at the airport by his buddies.
Joining the stars for the vacation will be their families, including significant others and children. Will they be trading beers for beach toys?!
However, there is one significant other fans won't be seeing: Snooki's husband Jionni LaValle, who posted on Instagram that he will not be appearing on the show. "I am CHOOSING TO NOT be on TV because I simply DO NOT like it," he wrote, going on to shoot down divorce rumors. "Nicole and I are doing great and became even stronger together while raising our kids."
In case you were concerned that the J.S. cast had lost their love of partying over the years, let this photo of Ronnie with his beer bong on the FIRST day of filming put your mind at ease.
MTV let fans weigh in on where the cast should reunite, with Miami winning out in the end.
MTV has yet to announce an official return date ("Coming F—king Soon" the promo says), but the cast just started filming, and production is expected to last around a month, so expect it sooner rather than later.
