VIDEO: Ronnie's Cheating Ways Slammed On Jersey Shore's Reunion Show

Ronnie - who admitted he "did a lot of messed up things” during season two - was in the cross hairs for his unfaithful ways toward girlfriend Sammi "Sweetheart" Giancola.

When host Julissa Bermudez questioned the actions of Jenni "J-WOWW" Farley - who alerted Sammi to Ronnie's wandering eye via anonymous note - J-WOWW defended her actions to Sammi, saying she specifically told her via note "because the result was Ronnie dogged you.

“Ronnie said that I wanted to hook up with him, and you believed him and not me," J-WOWW said, adding that she's rather hook up with Paul "Pauly D" Delvecchio than Ronnie.

The Situation chimed on on J-WOWW's behalf, as he said, "regardless of who wrote the note, who didn't write the note, who told you in person, the only person you could possibly be mad at was Ron," prompting an irritated Ronnie to bark at The Situation, "You're supposed to be my boy!"

The man with the golden abs responded, "Do you love that girl? Then you should be thanking me, because I'm the only one who goes up and talks to her when she's crying."

The Sitch wasn't totally in the clear however, as his attempted pickup of pal Vinny Guadagnino's girl Ramona caused Vinny to disband the trio viewers had come to know and love as “MVP” -- short for Mike, Vinny, Pauly.

"It might be MVP to him," Vinny said, disgusted with The Sitch's betrayal. "But it's VP to me."
