Lindsay Lohan is now in prison

The troubled actress entered the Beverly Hills courthouse at around 8.30 am Pacific Daylight Time today (20.07.10), where she was remanded in custody to begin her 90-day jail sentence for breaking the terms of her probation on her 2007 driving under the influence (DUI) charge.

Lindsay was in court with her on/off attorney Shawn Chapman Holley, when Judge Marsha Revel ordered the cameras to be cut off as the 24-year-old actress surrendered to authorities and was led away by bailiffs to begin her sentence at the Century Regional Detention Facility in Linwood, California.

During the brief hearing, Judge Revel admitted she had no idea how many days exactly Lindsay would serve, but because of overcrowding at the detention facility in Lynwood, California, it is likely she won't be incarcerated for more than three weeks.

She said: "I do not know exactly how long the jail will keep her… I can only impose the sentence."

Lindsay didn't speak during the brief court appearance, but nervously watched on, biting her nails.

It was also revealed in court that Robert Shapiro – who claimed to have quit as Lindsay's lawyer last night (19.07.10) – was never officially hired to represent her, and only worked as a "consultant" on the case.

Shapiro apparently joined Lindsay's legal team earlier in the week after Holley resigned, and then allowed her to stay in the Pickford Lofts sober living house he founded following the death of his son Brent to substance abuse.

Holley told the court: "Just to be clear, Mr. Shapiro acted as a consultant but was not an attorney on the case at any time."

Judge Revel – who confirmed he visited her yesterday to warn her he wouldn't be working with Lindsay - - answered: "I never actually relieved you, so you are Miss Lohan's attorney."

The judge also told Lindsay she had amended the conditions of her sentence slightly, ordering her to enter a rehabilitation facility within 24 hours of leaving prison instead of the 48 she originally set.

She said: "I would like the transition to be sooner rather than later and I would like to speak to counsel about it in more detail."
