Troubled actress Lindsay Lohan was all smiles as she and her attorney Shawn Chapman Holley entered the courthouse today. Lohan wore a white pleated skirt, a black jacket and Christian Louboutin heels.

But the smiles soon faded as a judge revoked LiLo’s probation and remanded her into the custody. Lohan is headed back to her jail cell at a woman’s detention center in LA.

Judge Elden Fox, who took over her case from Judge Marsha Revel, denied Lohan’s bond and sent her back to jail for failing 2 drug tests.

According to TMZ, Lohan appeared shocked as the sentencing was handed down. She looked at her attorney and was immediately handcuffed and transported to jail covered by a blanket.

Judge Revel originally sentenced Lohan to 90 days in jail followed by 90 days in a drug rehab program. But celebrities have made such a mockery of the justice system in LA that Lindsay was able to serve less than 2 weeks in jail and almost 3 weeks in a rehab facility in UCLA.

The star struck UCLA doctors recommended an early release for Lindsay after they determined she was not a substance abuser.

According to TMZ:

Los Angeles County sheriff’s spokesman Steve Whitmore told reporters Lindsay will be housed in “administrative segregation” because of her celebrity status for her safety and the safety of the jail system. He also said the only way she could be released before her probation hearing on oct 22 is if the judge issues another order

Update I, 1:38 pm ET:

Lindsay Lohan posted a $300,000 bond and was released from jail late last night. Judge Eldin Fox revoked Lohan’s bond Friday and ordered her to jail until her revocation hearing on Oct. 22. But Lohan’s attorney, Shawn Chapman Holley, filed an appeal of the decision right before court closed yesterday.

Lohan must wear a SCRAM ankle bracelet and report to her probation officer within 24 hours.

“I pray to God that Shawn does the right thing and advises her to go right into rehab now, and show the judge she’s serious, because in 30 days when she goes back before the judge he can do whatever he wants,” Michael Lohan, her father, told CNN.
