Some reunions are civil and mature - thank you, Nick and Jessica.
Others, meanwhile, are hilarious and spiteful - who else but you, Paris and Lindsay?
Despite a recent interview in which Hilton claimed there was no feud between these awful people, the encounter between the painful duo last weekend in Malibu would suggest otherwise. For some reason, each were invited to a party there.
Paris responded to the presence of her bitter rival with non-stop laughter. According to Page Six, the new music video star "made it a point to whisper and laugh very loudly the entire time" at the Polaroid Beach House. Lohan, conversely, escaped the situation by slipping away to a back bedroom with boy toy, Harry Morton.
The Gossip has little doubt about what went on there.
Later, however, Hilton walked by and one of Morton's friends faked a kick to her read end, according to a witness. He only missed, we presume, because he couldn't tell the difference between it and her face.
