The diminutive `Jersey Shore` star is currently shooting the fourth series of the MTV show in Italy and despite a visit from Jionni last week, the couple - who have been dating for almost eight moths - couldn`t stop fighting and make their relationship work.

A friend told Life & Style magazine: "He went to visit her in Italy this past week. They fought a lot while he was there and have called it quits.

"He said it was hard for them to be apart, and that with the whole world knowing her past, he finds it very hard to trust her. He said that as far as he was concerned, if she did anything wrong in Italy, it was over."

"When he got back from Italy, he called a mutual friend [of ours] and said that they had broken up. I think he was just really sad about being away from her so much. I`m not sure who broke up with whom -- it seems to be mutual because of the distance and the time apart."

Snooki has previously hooked up with `Jersey Shore` co-star Mike `The Situation` Sorrentino and Vinny Guadagnino on the show.
