Paris Hilton appears to have threatened Lindsay Lohan following an assault on her brother.
The hotel heiress was on family lockdown after her younger brother Barron was allegedly beaten by one of Lindsay's close friends.
Barron posted a photo of his bruised and cut up face, following the brawl on Friday night in Miami, Florida.
Big sister Paris was quick to comment on the image, breaking her silence over the attack.
"They both will pay for what they did. No one f***s with my family and gets away with it!!" she wrote.
Barron, 24, is thought to believe that the attack was masterminded by Lindsay after she accused him of talking about her to her boyfriend while at a party held as part of the Maimi Art Basel event, TMZ claimed.
"Barron told cops Lindsay approached him at the party with a male friend and began screaming: 'You talk sh*t about me to my boyfriend, this is what you get.'
"As the guy proceeded to pummel Barron, Hilton claims Lindsay was laughing and egging him on," TMZ reported.
Police were called to the scene where they spoke to Barron, who reportedly said he didn't know his attacker's identity but is adamant that Lindsay was behind it.
This isn't the first disturbance between Lindsay and the Hilton's. Paris, 32, and Lindsay have a history of long-standing feuds with each other.
In 2006 Paris was caught on film making fun of the Mean Girls actress with her close friend Brandon Davis.
Lindsay's father Michael denies that his daughter had anything to do with the incident.
