An arrest warrant has been issued Lindsay Lohan after she missed a probation hearing today in L.A.

Her lawyer, Shawn Chapman Holley, said Lohan couldn't return from France for the court date because she lost her passport -- but Judge Marsha Revel still came down hard on the actress.

Revel issued a bench warrant for Lindsay's arrest when she lands back in L.A. and set her bail at $100,000.

If Lohan posts bail, she'll be forced her to wear a SCRAM bracelet and submit to random drug testing. She's also forbidden from drinking alcohol.

While in France, Lindsay has been spotted out partying -- check out the pics above.
