ET has learned that Ronnie Ortiz-Magro and Sammi "Sweetheart" Giancola of MTV's "Jersey Shore" have split and it seems Sammi wants nothing to do with her reality-show co-star.
A source tells ET that their private drama has become public news on Facebook with Sammi unfriending all of Ronnie's associates from her page.
Ronnie and Sammi have had an on-and-off relationship that has turned violent at times. On the show Sammi has been caught fighting with her now ex-boyfriend and even hitting him in the face.
Cameras have also captured Ronnie in dubious situations with women on several occasions throughout the show's first two seasons.
"Jersey Shore" airs Thursday nights on MTV.
