Do you think jail will straighten up Lindsay Lohan?

The 'Mean Girls' actress must begin serving her sentence on July 20, however she likely won't serve the entire 90 days. Many female inmates in Lohan's situation only serve about 25% of their sentence, meaning that the star will only spend about 23 days behind bars. Immediately after leaving jail, Lohan will spend another 90 days at an in-patient rehab facility.
