Who Throws First Slap on 'Jersey Shore' Season 2? (VIDEO)

Since everyone in the house hates Angelina Pivarnick, one might assume she'd be on the receiving end of the second season's first slap on 'Jersey Shore' (Thu., 10PM ET on MTV). But no, she was the source of the gesture -- and unrequited love made her do it.

Angelina got really drunk and told Paul "DJ Pauly D" DelVecchio, "I love you ... I think about you every day."

His reaction was far from heart-warming: "Me and Situation did hook up on Angelina at one point," he later explained. "I don't have those feelings for Angelina, and she's fine with that."

Evidently not. The Situation lowered his sunglasses to discover that the girl had indeed started crying. Angelina said, "You just don't care, like seriously!" Thwack across Pauly D's face.

The Situation suggested she go to bed. "You're drunk -- you're acting [beep]-up right now." Pauly D's strategy was to "sit back. I'm like, I can't believe this girl just smacked me, so I'm just gonna shut up and hope she goes away." She didn't.
