Paris Hilton's younger brother, Barron, has filed a police report after being brutally beaten at a house party in Miami on Friday night, TMZ reports, at which he claims Lindsay Lohan orchestrated the attack.

The 24-year-old says he was approached by a male friend of Lohan's at the party, who started pummeling him in the face as Lohan allegedly screamed, "You talk sh*t about me to my boyfriend, this is what you get," while laughing and egging on the beating.

Michael Lohan, Lindsay Lohan's father, told TMZ that his daughter has an alibi and was not at the party while the incident occurred, having left earlier in the night. Video footage obtained by TMZ, however, shows that Lohan was still at the party at 11 a.m. the next morning when she was confronted by Barron Hilton and his friends. She has been staying at the Miami mansion while attending a local art festival.

While Barron Hilton told police he didn't know the identity of his attacker, he maintains that Lindsay Lohan orchestrated the entire thing. Multiple sources say that cocaine and alcohol were in abundance at the mansion party, but others have clarified that Lohan, who is now sober, was not partaking and even threw some people out for using drugs.

The Hiltons tell TMZ that Barron's cuts and bruises on his face were so bad that he was advised to seek medical attention immediately. He was given a private transport to the University of Miami Hospital, where he received treatment and a CT scan.

The Hiltons and Lohans have had bad blood for years, beginning in 2006 when Paris Hilton's friend Brandon Davis was filmed by paparazzi ranting about Lindsay Lohan having a "firecrotch" while Hilton giggled in the background.
