Chock full of credibility, Linday Lohan is claiming she did not drunkenly chase her assistant before being arrested for drunk driving early yesterday morning... and that the cocaine found IN HER POCKET belonged to someone else.

First lies first: Sources connected to the actress tell TMZ both Lindsay, who was driving a Denali, and the Escalade in front of her, driven by the mother of Lindsay's former assistant, were both being chased in a "unsafe and threatening" manner.
