A Los Angeles judge sentenced Lohan to 120 days for violating her probation by taking a designer necklace, a charge the judge reduced from felony grand theft to a misdemeanor. The actress's attorneys appealed the jail sentence, Lohan's fourth, and she was freed on bond after a few hours behind bars.
The actress will also have to do 360 hours of community service at the Downtown Women's Center on Skid Row. Her work at the morgue may include observing procedures in the autopsy room.
"She won't be exposed to bodies, per se, but she will be in the area surrounding the autopsy room," Artiga said. "She will have to take out the trash, the soiled linens, the dirty rags, the bloody trash."
Artiga said Lohan will be exposed to vomit, urine and feces.
Lohan received a standing ovation from the audience during a taping of the "Tonight Show" scheduled to air Tuesday.
The audience's warm reception of the troubled actress was reported by a person connected with the show, who spoke on condition of anonymity because NBC had announced Lohan's appearance but no other details were released.
Host Jay Leno reportedly asked the 24-year-old about touchy subjects including her court appearance and brief jailing Friday, her family and what she's learned from her experiences.
Lohan was a late addition to Tuesday's show, bumping a scheduled guest, Broadway star Kristin Chenoweth, to another date.
Lohan told the show's audience that she is playing the wife of John Gotti Jr. in the crime family movie, "Gotti: Three Generations." Her casting in the role was announced last week but it was unclear if her legal problems might affect it.
Lohan told Leno she found the sentence "shocking" and said it left her "kind of numb."
