Lindsay Lohan looking visibly upset makes a quick angry dash out of a Matthieu Chedid concert given this evening during the Cannes Film Festival 2010 in Cannes, France on May 17, 2010. Oops maybe Lindsay is upset because she found out volcanic ash may cause her to miss her court hearing on Thursday for her probation progress report. Should be interesting wonder if the judge will actually issue the bench warrent for her arrest he should or will it be another case on celebrity justice. Photos: Fame Pictures
