Lindsay Lohan: From the Riviera to Up the River?

Starlet threatened with arrest warrant if she doesn't show up for court this week

Maybe it's time for Lindsay Lohan to say au revoir to Cannes.

The scene-making starlet had actually better allez, because a Los Angeles judge said today that Lohan's presence is required in court on Thursday for her next probation hearing.

If she's not there, a bench warrant could be issued for her arrest, L.A. District Attorney's Office spokeswoman Jane Robison tells E! News.

What a shame, considering she just landed (on her butt) in France.

Lohan flew out from New York on Friday morning and arrived in Nice on Sunday, though we like to think that she knew as well as the media did that she had a DUI progress report coming up this week.

Following a pair of DUI arrests in 2007, the 23-year-old was ordered to complete an 18-month alcohol education program. A judge deemed her "in compliance" with the court in February and her lawyer has confirmed that Lohan needs about two and a half more weeks to complete the terms of her three years of probation.

We doubt she learned anything useful while yachting on the French Riviera, however.
