LOS ANGELES (AP) — Lindsay Lohan's stay in the Los Angeles County Jail will be significantly shortened by jail overcrowding.A judge sentenced her Wednesday to 30 days in jail after she acknowledged she recently violated court orders by getting booted from a community service assignment at a women's shelter.Sheriff's officials say Lohan may be at the jail for only a few hours. The actual length of the term will be set by the Sheriff's Department, which oversees county lockups.The 25-year-old actress has until Nov. 9 to report for her jail term, and Superior Court Judge Stephanie Sautner ruled she cannot serve house arrest, as she did previously this year.The sentence also requires Lohan to perform community service assignments at the county morgue, undergo psychotherapy sessions, and appear monthly at court hearings through March.
