Lilo faces 23 hours a day curled up in a tiny cell inside the Lynwood correctional facility in Los Angeles, after breaking probation following a 2007 drink-driving charge.
Current Lynwood inmate Tamara Haley, who is doing time for heroin possession and prostitution, told The Sun that "everyone [in the jail] will want a piece of her. It will make them famous if they hurt Lindsay Lohan.
"Or if you get her to cry, the whole ward will laugh and people will love it - even the guards.
"The gay inmates wear their shirts inside out to let others know they are available. So if Lindsay doesn't want someone to grab her ass she'd better keep her shirt on straight. Women grab each other like animals when the guards aren't looking. It's disgusting."
Lindsay is currently trying to get out of her jail term before her surrender date of July 20. Overcrowded conditions may see her 90-day sentence shortened to 23 days.
Inmate Tamara continued: "She'll be segregated from the general population but where she's going it is even worse. It's the wing where the murderers are.
"I don't think they will actually be able to get to her, but you never know. At the very least some of those hardcases will try to scare her. They'll scream stuff to her from their cells.
"I've been in segregation and it was rough. The lights are on the whole time. You hear people screaming all night long. The cells are filthy and kept brutally cold. You get one tiny blanket and that's it.
"There's an infection going around now. You can barely sleep at night from all the coughing. And there are girls with body lice."
