Lohan's spokesman, Steve Honig, declined to comment on what prompted the meeting. Part of her probation includes no alcohol, but a source told Eyewitness News that she may have violated that rule by drinking during a rooftop party at her Venice home on June 12.
Upon completion of the conference, Superior Court Judge Stephanie Sautner decided that Lohan did not violate her probation.
Lohan's attorney said the Beverly Hills judge who originally signed the order asked for controlled substance testing, but it was in effect only until Feb. 25.
"I just want to say, she's done nothing wrong. She's done everything right," said Lohan's attorney, Shawn Holley. "It's not a violation of her probation."
"She was no to be tested at all after February 25th," she said. "But during the time period she was to be tested, it was simply for controlled substances, not for alcohol."
Sautner did tell Lohan, however, that she is guilty of "extremely poor judgment." She prohibited Lohan from parties at her house and sand said she can only have one friend over at a time.
After court, Lohan tweeted, "Thank you to all of my fans for your support. Sending you Love and Light. xo"
Thursday's conference comes toward the end of what was expected to be a 35-day stint for Lohan on house arrest for violating her probation for taking a $2,500 necklace from a Venice jewelry store without permission.
The "Mean Girls" star has been on probation for a misdemeanor DUI case stemming from a pair of DUI arrests in May 2007 and July 2007.
Lohan has been confined to her Venice Beach home since May. She is expected to be released from house arrest in July. The 24-year-old would then complete the 480 hours of community service the judge also imposed.
The actress has spent the past four years in and out of court and even spent 13 days in a Los Angeles County jail last summer for violating her probation. She has also spent eight months in substance abuse and rehabilitation programs.
Lohan is scheduled for another hearing July 21.
