Lindsay Lohan Pleads Not Guilty To Felony Grand Theft, Next Hearing Set For February 23rd

Lindsay Lohan wore an angelic white dress to court today, perhaps to help reinforce her "not guilty" plea, but perhaps she and lawyer Shawn Chapman Holley shouldn't have been smiling the whole time?

The 24-year-old starlet was charged with felony grand theft for allegedly stealing a $2,500 necklace from Venice jewelry store Kamofie & Company on January 22nd.

Judge Schwartz set bail for $20,000, plus an additional $20,000 for Lindsay violating probation in her DUI case - which comes to a grand total of $40,000. (Linds posted the necessary $4,000 bail, officials confirm, and was released shortly after.)

Lindsay plead not guilty, but the judge still handed her a stern warning:

"You're in a different situation now that a felony has been filed against you. Although people have been courteous, in this court's opinion, in only requesting $20,000 in the probation violation, you now have a pending felony case. If you violate the law, I will remand you and set no bail. You're no different than anyone else, so please don't push your luck, because I'm telling you, things will be different."

Lohan's next hearing is scheduled for February 23rd. Will LiLo be lucky enough to stay out of trouble until then?

Because this is a felony charge, what other standard procedure did Lindsay have to submit to? And was she cooperative? Click below the cut to find out more deets!
