Sammi "Sweetheart" Giancola and Ronnie Magro are finito.

"They are done," a source close to the Jersey Shore duo tells Usmagazine.com, adding, there was "major tension" between them as they promoted the MTV hit's third season.

Indeed, another insider noted that the couple were "barely speaking to each other" during a Jan. 6 appearance on Good Morning America.

The couple's romance blossomed as they filmed the smash reality hit in Seaside Heights, NJ in 2009. Their combative relationship endured even after many bumps in the road, including Magro's numerous hookups with other women in Miami.

"I'm embarrassed about what I did to her," Magro said at the time.

Last week, Magro began Tweeting about "Single Ronnie."

For his part, castmate Pauly D told UsMagazine.com he prefers his pal single. "I love single Ronnie," he said. "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!

@Karen Gleeson Erckenbrack- So agree with u Karen! Ronnies the one who cheated, therefore he should have left the house..only right!

If I never have to see this couple become verbally or physically abusive again, I will start to enjoy the show much more. They have the most immature, jealous, disrespectful, unfaithful, non-trusting relationship I have EVER seen!!! Please make the torture of watching this viscous cycle of fighting STOP. PLEASE!!!

I am glad she left him or he left her, whatever the case maybe.. neither of them belong with each other.. Ronnie dogs her.. how do you treat someone so badly if you LOVE THEM?

Sammie is beautiful and could have any man she wants. I'm glad she got rid of Ronnie. He is the one who lost out

Oh please, Sammi is annoying! Just as Mike said in one of the 2011 episodes....if she's that hurt, then leave him! She's like a friggin' stalker, up his behind all day like his CO! Seriously, it's pathetic!

could you imagine watching someone cheat on you...you would all act the same way if you had to go through everything she did and you dont even know her so you shouldn't judge her

Sammi is so dam stupid. Ronnie keeps on playing you over and over again. I love the single Ronnie. As for you, your girls tried to look out for you, but you just couldnt accept the truth. Hope Jwow kicks your ass over and over.

They were still together New Year's Eve, but stuff obsiously went down. See http://bit.ly/euCB2I for more on their Twitter war etc...

Sammi is frikin DUH in the head. I don't get why she is hating on her use-to-be friends...she asked them to tell her, they told her in a way that at the time thought was easier...and than who gets all the anger about Ronnie cheating?? Snookie and Jwild because they told the truth...obviously Sammi doesn't know how to be a friend..and the saying "Chicks before Di cKs" do not apply to her

This latest breakup between Sammi and Ronnie has been clear for over a week now. For the play by play commentary of what's gone down, search for "payattentionto blog"

She's a stuck up snob and a total waste of a "personality" on the show.
January 11, 2011 - 4:46pm Malia Da Lancey
Good maybe now she'll quit the show she's the most boring of the cast. I'm so happy Jenny socked her in the face. Loser
January 11, 2011 - 3:57pm Kristen Perez
Well at least she got to sock him in the face before they broke up!

agreed she sucks at life i totally agreed with snooki when she said she didnt know how she had friends...she is a miserable person i hope she finds her way she is getting to be a little too old to be so ridiculous she alienates everyone...watching her aggravates me
