The 24-year-old actress – who started her sentence at the Century Regional Detention Facility in Lynwood, California, last Tuesday (20.07.10) – has become close to some other inmates after settling in.
Her lawyer, Shawn Chapman Holley, told UsMagazine.com: "She is doing fine. She has made some friends."
Lindsay is expected to serve less than 14 days of the 90-day sentence she was given for breaching the terms of probation set for her in 2007 for a driving under the influence (DUI) conviction.
While Holley could not confirm an exact release date, she explained: "I would like to ensure that she has received all the time credits to which she is entitled [from her previous time in custody]. I am hopeful that her sentence will be reduced once those credits are properly factored in."
And Lindsay's lawyer – who briefly quit last week before taking up the actress' case again – insisted numerous reports of preferential treatment for the star were incorrect.
Holley revealed: "We are not asking for special treatment from the court or the sheriff, nor is she receiving special treatment."
It was revealed last week the actress was cheered by other inmates shouting "we love you Lindsay" as she arrived at the prison.
Prisoner Tiffany Hawes, who was being released from the centre at the time of the actress' arrival, said: "Lindsay was crying when she came in. She was handcuffed but seemed calm. We all started saying, 'God bless you Lindsay,' and saying, 'Hi' to her and then she smiled at us."
