Lohan was also sentenced to 480 hours of community service, 120 of which she will complete by picking up trash, cleaning bathrooms, and mopping floors at the Los Angeles County Department of Coroner's facility.
"She'll be doing basic janitorial work," Coroner Assistant Chief Ed Winter told People magazine Monday. "She won't be handling any dead bodies, but she'll certainly see them."
Lohan must finish the last 360 hours of service at the Downtown Women's Center, a homeless shelter located on L.A.'s Skid Row.
But there might be more punishment in store for Lohan.
She faces a June 3 trial for misdemeanor theft, which could get her a maximum penalty of another year in jail.
Besides discussing her recent court appearances, Lohan also reconfirmed that she's playing the wife of John Gotti Jr. in the crime movie "Gotti: Three Generations." (Lohan was originally vying to play Victoria Gotti; her casting as Kim Gotti was announced last week but it's unclear if her legal drama will affect her participation in the movie.)
Lohan said fans have been very supportive despite her personal troubles.
"I feel that I've let a lot of my fans down by putting myself in situations when I wasn't thinking clearly. And I just really want to be the person that I aspire to be," she said. "Be the actress and be in this industry and be in movies and do what I love to do and bring characters to life that people can relate to and my fans have been really supportive of me doing that."
She also said she's learned from her missteps and plans on working toward her goals.
"Being young and being in the position I was in, you don't really take the time to appreciate what you have and it's all kind of whirlwind and people make decisions for you," she said. "But I'm not a kid anymore. I'm 24. I've made a lot of mistakes and I recognize that. But I'm in the clear now and I feel like as long as I stay focused, then I will be able to achieve what I want to achieve."
