Paris Hilton's younger brother, Barron, attended a party in Miami last night (Nov. 5) where someone accused him of trash-talking Lindsay Lohan, as sources tell TMZ. The 24-year-old was allegedly approached by a male friend of Lohan's, who punched him in the face while Lohan allegedly watched and laughed.

Following the incident, Barron contacted the police and reported that Lohan had orchestrated the beating. He claims that Lohan had approached him with a male friend and screamed, "You talk sh*t about me to my boyfriend, this is what you get" before the punching began. Barron does not know the identity of his attacker, only that he is connected to Lindsay Lohan. Lohan, however, does not currently have a boyfriend that anyone knows about, "The Canyons" star having denied her romantic connection to co-star Michael Neeson, and has said that she's happy being single at the moment.

Michael Lohan, Lindsay's father, told TMZ that his daughter had nothing to do with the attack and that she had left the Miami mansion before the incident occured. He claims that several witnesses, including security guards, can back up Lindsay Lohan's alibi. The 27-year-old star is currently in Miami for an art festival.

The Lohans and the Hiltons have apparently had "bad blood" between them for years, despite Lohan and Paris Hilton having been friends and party buddies back in the day. Paris Hilton's friend, Brandon Davis, began the family feud when in 2006, he went on a rant about Lindsay Lohan having a "firecrotch" that "s**ts freckles" in front of paparazzi while Hilton laughed. Davis is also known for calling Lohan a "coked out w***e" and a "loser."
