Asked by TV's Access Hollywood late Tuesday if there was anything the actress, 21, wanted "to get out there" about the charges against her, Lohan responded in an email to the show's Billy Bush, who had just spoken about her on CNN:
"Yes. I am innocent ... did not do drugs they're not mine."
Amid reports from police that they had received a 911 call from the mother of Lohan's former personal assistant, saying that Lohan was chasing her in an SUV, Lohan also said in her email, "I was almost hit by my assistant Tarin's mom."
Police found Lohan and the woman in a "heated debate" in the parking lot of Santa Monica's Civic Auditorium at about 1:30 a.m., according to Santa Monica police Lt. Alex Padilla.
Lohan concluded her brief message with, "I appreciate everyone giving me my privacy."
More on Lindsay
Lohan's parents have both expressed their despair over their daughter's troubles. Dina Lohan told TV's The Insider that she is "sick over this," while estranged father Michael Lohan told CNN's Larry King Live on Tuesday that he feels partly responsible for Lindsay's problems.
"Of course I do," he said. "If I didn't I'd be a liar. I made some really stupid choices in my life."
This was Lohan's second drinking-related arrest in three months. Her attorney, Blair Berk, said that the actress – who had worn an alcohol-monitoring ankle bracelet since her July 13 release from 45 days in rehab – had suffered a relapse and is "presently receiving medical care."
