The judge in Lindsay Lohan's probation violation case Wednesday ordered the troubled actress to serve 30 days in jail, followed by a carefully prescribed regimen of community service and psychological counseling.

Wielding the stick of an additional 270 days in jail if Lohan, 25, does not comply with the court's requirements, Judge Stephanie Sautner ordered her to report Tuesday to Century Regional Detention Facility, where Lohan previously served time. Sautner specified, "You are not to be eligible for house arrest, electronic monitoring [or] any other early release other than that required by law."

In reality, however, the initial 30-day sentence will be significantly shortened by jail overcrowding, with Lohan likely serving only about six days, The Associated Press reported. The actual length of the term will be set by the Sheriff's Department, which oversees county lockups.

After the incarceration, Lohan must then complete 12 days of community service at the county morgue and attend four 45-minute psychological counseling sessions in each of the four monthlong periods, ending Dec. 14, Jan. 17, Feb. 15 and March 19, followed by some additional days and sessions to round out the sentence.

"From what I see of you," Sautner told the "Mean Girls" star, "you need a structure."
