The "Rumor" singer planned to start her community service this 12, reported Ace Showbiz.
Lohan, 28, was ordered to do the remaining hours of community service at a preschool in Brooklyn, Duffield Children's Center.
The deadline of the completion was set on May 28. A Los Angeles court ordered her to do 125 hours of community service as part of her probation in February, due to her reckless-driving case in 2012.
The "Mean Girls" star has completed nine hours and 45 minutes of her community service so far.
Her 125-hour community service was given after the judge found the documentation for her previous 240 hours of community service was not entirely valid.
