What's one of the most important parts of every bride's wedding? Her bridesmaids, of course.

Over the weekend -- and just days before their best gal pal's nuptials -- Jenni Farley, Deena Cortese and Sammi Giancola reunited with Nicole Polizzi for a '20s-themed rehearsal dinner in the Garden State. A "Jersey Shore" reunion TOTALLY worthy of a fist pump, if you ask us.

"At rehearsal with my girlies!!!! ❤️ @jennijwowwmtv @deenanicolemtv @sammisweetheart," the soon-to-be Mrs. Jionni LaValle -- who also celebrated her 27th birthday on Sunday -- captioned the adorable pic above on Instagram.

Enjoying the last moments of bachelorette life, the "Snooki & JWOWW" star partied the night away in style, looking stunning in a long white gown as she channeled her inner Daisy Buchanan. Meanwhile, her BFFs looked equally gorgeous in all-black attire.

And like any dutiful and loyal bridal party, Deena and Jenni couldn't help but beam with pride as they counted down the days to their bestie's special day.
