They've spent their last few summers in Seaside Heights -- so seeing the destruction Hurricane Sandy has brought to the area has the "Jersey Shore" cast at a loss for words.
The photo above is of the boardwalk, pier and roller coaster that were featured on the show ... all under water.
"Holding back my tears to finish out my day here in la but my thoughts are with my shore family and everyone there helping," Jenni "Jwoww" Farley tweeted this afternoon.
"Crying over the damage the jersey shore and my town received. Legit boats are on the roads I used to drive. I cannot believe this," she added while tweeting a photo of fiance Roger Mathews jet-skiing down a street.
"Seeing seaside and what has happened to my hometown is beyond devastating. I have no words," added Sammi "Sweetheart" Giancola. "For all the people that have gone through this hurricane and destruction, my heart goes out to you."
