Lindsay Lohan reported for work Wednesday at Brooklyn Community Services' Duffield Children's Center, in her bid to complete just over 115 hours of community service by May 28.

"So happy to be finally helping out all the kids at @WeAreBCS," the actress tweeted Wednesday morning. "I just hope that I can make a difference to their lives."

The actress later posted an Instagram image showing herself in a smiling embrace with an unidentified woman and child. TMZ.com said the boy in the photo was Donovan, 5, who had appeared in scenes of Lohan's community service at the same facility in "Lindsay," an eight-part documentary that ran on OWN last year.

"All is well," mother Dina Lohan told Newsday. "My daughter is back home in New York safe and sound" and "excited to see the children she worked with while filming her Oprah documentary."

TMZ, which posted a photo of Lohan, 28, arriving at Duffield carrying a copy of the Quran, said the actress had arrived two hours later than initially expected. However, BCS Early Childhood Education Director Ivonne Lopez told People magazine that the "Freaky Friday" and "Mean Girls" star "got here super early . . . I don't know [the] exact time but she was here early."

News outlets that have calculated the mathematics of Lohan's remaining hours say it will be difficult for the actress to complete them on time.

In February, a Los Angeles judge gave Lohan three months to complete 125 hours of community service, stemming from her March 2013 sentence for reckless driving after her Porsche and a truck collided on Pacific Coast Highway. On May 7, the court found she had finished fewer than 10 hours and ordered the actress to put in the remaining time by May 28 or face unspecified "consequences."
