Lindsay Lohan was briefly jailed again on Friday after a rollercoaster day in which a judge downgraded her jewelry theft charge, but sentenced the actress to four months behind bars for violating her probation.

Looking confused and distressed, Lohan -- who was locked up for two weeks last summer -- was taken immediately to jail from court after a day-long preliminary hearing on charges that she stole a $2,500 gold necklace from a store in January.

The "Mean Girls" actress was ordered to stand trial on June 3 but the jewelry charge was reduced to a misdemeanor from a more serious felony, and will cut to one year her maximum time behind bars if eventually convicted.

Los Angeles judge Stephanie Sautner, however, felt the evidence on Friday suggested Lohan intended to steal the jewelry.

She therefore ruled Lohan had violated her probation for a 2007 drunk driving and cocaine possession incident, and sentenced her to 120 days jail and 480 hours community service in a morgue and women's prison.

Lohan's lawyer filed an immediate appeal and Lohan's camp scrambled to post $75,000 bail and secure her release from custody pending an appeal hearing.

She was released late on Friday after about five hours, according to the Los Angeles County Sheriff's Department website.
