Lindsay Lohan pleaded not guilty Wednesday to felony grand theft of a $2,500 necklace — a case that could return the troubled starlet to jail rather than the big screen.

She entered the plea through her attorney Shawn Chapman Holley after a judge scolded her about following the law.

“Look around this room,” Superior Court Judge Keith Schwartz told Lohan. “Everybody else has to follow the law. You’re no different than anyone else. So please, don’t push your luck.”

Schwartz set bail at $40,000. He said it appeared Lohan had violated her probation in a 2007 drunken driving case and warned that if she violated the law while free on bail he would have her arrested and held.

Lohan spoke little during the hearing except to acknowledge her name and that she understood the charge and the possible consequences.

The “Mean Girls” star was met by a swarm of photographers when she arrived at the courthouse in a white dress and sunglasses.

Prosecutors claim the 24-year-old starlet took the necklace in January.

If convicted of the theft charge, Lohan could face up to three years in state prison.

Holley said Lohan was entering an early disposition program where she could work out a deal to keep the case from going to trial.

She said Lohan has received good reports from her probation officer and has not failed any drug screens.

Prosecutor Danette Meyers rejected the idea that Lohan has been well-behaved.

“Well, a good probationer doesn’t pick up a new case,” Meyers said.

Schwartz ordered Lohan not to have any contact with the jewelry store that reported the necklace missing. The order came after Meyers said that someone sent the store flowers on Lohan’s behalf after police started their investigation.

The jewelry case is not Lohan’s only concern. Prosecutors in Riverside County are considering whether to charge the actress with battery for an altercation with a rehab worker at the Betty Ford Center in December.

The worker was fired after giving an on-camera interview to celebrity website TMZ, but district attorney’s spokesman John Hall has said the allegation against Lohan was under review.

The threat of incarceration has hung over Lohan since May, when a judge handling her DUI case determined she violated her probation by missing weekly alcohol education classes.

Her three stints in jail in the past three years have all been shortened by overcrowding and the fact that she could not be held without bail on a misdemeanor.

5 finger discount sales used to be a great deal til in-store video cameras became the norm. Lohan, who just left three months of rehab, is being charged with Felony Grand Theft for allegedly stealing jewelry from a Los Angeles store last week, TMZ reports. The charges will be filed as early as Monday.

The charges come after the LAPD began to investigate video surveillance that showed her with the necklace in the store, and photos of Lohan a week later showing her wearing a necklace that looks astoundingly similar. After TMZ broke the story about her alleged theft, a Lohan friend returned the necklace to the store.

If she’s guilty, Lohan could face jail time, especially since a conviction would violate the terms of her probation.

Lohan narrowly missed being disciplined for an alleged drunken incident while in rehab, and this new trouble could not only send her back to jail, but scuttle her role in a thinly veiled autobiographical film that was supposed to be her comeback.

For her part, Lohan says that the accusations are “bulls**t” and not to believe them. She says that she “borrowed” the necklace and TMZ says she’ll fight the charges.
