Amid reports that she failed a court-ordered drug test, Lindsay Lohan insists she's clean, and the Los Angeles District Attorney's office says it has received nothing to indicate that the actress violated the terms of her probation.
"We are not commenting on it," the Los Angeles D.A.'s spokeswoman, Jane Robison, told ABCNews.com. "The judge has not issued a hearing and we do not have any official report."
She added, "We do not expect to see a report [of the drug test results] today, maybe on Monday."
Earlier today, TMZ.com claimed that the 24-year-old actress had failed a court mandated drug test and tested positive for cocaine. Lohan refuted that report to Usmagazine.com.
"I'm fine," she said, offering her own interpretation of TMZ: "They're all nuts."
Lohan's lawyers did not immediately respond to ABCNews.com's requests for comment.
Lohan left a rehab program at UCLA Medical Center on Aug. 24 after 23 days of treatment. Earlier in August, she was released from jail after serving just 13 days of a 90 day sentence for violating her probation stemming from a 2007 DUI case.
At a hearing last month, Beverly Hills judge Elden Fox ordered Lohan to go to weekly psychotherapy and behavioral therapy sessions, in addition to 12-step dependency program meetings and mandatory drug tests. Fox said if Lohan was found to be in violation of the terms of her probation, she could go to jail again for 30 days.
The failed drug test reports are the latest to plague Lohan. Last month, a papparzzo claimed he saw her hit a baby's stroller with her Maserati and drive away. No charges were filed relating to the alleged incident.
Even before she hit the bottom of the barrel, Lindsay Lohan was apparently plotting a way to crawl back to the top.
In an interview with Vanity Fair magazine, done prior to her latest jail and rehab stint, Lohan said she wants A-list status in Hollywood again, by any means necessary.
"I want my career back," she said. "I want the respect that I had when I was doing great movies. And if that takes not going out to a club at night, then so be it. It's not fun anyway.
"I don't care what anyone says. I know that I'm a damn good actress," she continued. "And I know that in my past I was young and irresponsible, but that's what growing up is. You learn from your mistakes."
Lohan appeared on Vanity Fair's cover and in the magazine, lounging on the beach, evoking old Hollywood glamour. Her problems, however, are firmly in the camp of today's tabloid-prone celebrities.
A probation report released in July revealed that Lohan has prescriptions for the antidepressants Zoloft and Trazodone; Adderall, a stimulant used to control attention-deficit hyperactivity disorder; the acid reflux medicine Nexium and the powerful painkiller Dilaudid.
"I've never abused prescription drugs," Lohan said.
