WATM reports Sammi and Ronnie are officially dunzo.
Sources close to the Jersey Shore pair say there is "major tension" between them and that "they're done."
There's no word on what exactly caused the split, but Ronnie's cheating ways and Sammi's mood swings have caused problems between them in the past.
Fellow cast member Pauly D says a split would be for the best. "I love single Ronnie. When he's doing the relationship thing, I let him do his thing, I don't get involved. When he's with Sammi he's a different person. She's a difficult woman!" he says.
