Lindsay Lohan has blasted Sienna Miller as a "no talent crackhead" while claiming herself to be the "greatest actress in the world".
The troubled Hollywood star, who was arrested last month on drink-driving and drug charges, also unleashes a torrent of abuse against fellow actors Scarlett Johansson and Keira Knightey.
The 21-year-old calls Johansson "fat and ugly" and Knightley is a "flat, shallow, cardboard cutout of an actress," according to reports in the National Enquirer.

Lohan has a history of falling out with young female Hollywood stars - from Hilary Duff to Paris Hilton - no actress seems to have been spared her wrath.
She was due to work with Knightley earlier this year in Dylan Thomas biopic, The Best Time Of Our Lives, but allegedly dropped out over financial negotiations.
Miller stepped into the role at the last minute and developed a close bond with Knightley.
According to Lohan, Keira is a 'cardboard cut of an actress',
while Johansson is 'ugly and fat'
Her feud with Johansson first surfaced last year when she co-starred with the actress's ex-boyfriend, Jared Leto, in Chapter 27. She allegedly scribbled obscenities about Johansson on the wall of a New York nightclub.
Lohan was arrested for investigation of misdemeanor driving under the influence and with a suspended license, and felony cocaine possession.
Besides her personal troubles, Lohan is also struggling with her career.
Despite winning high praise for her performances in Bobby and Georgia Rules, her latest film, I Know Who Killed Me, has been dismissed by critics as one of the worst of the year.
