On Eve of Reporting to Jail, LiLo's a 'Mess'

Lindsay Lohan starts her 90-day sentence for a probation violation tomorrow, and the Tinseltown trainwreck is a "nervous, fidgety mess," a source tells People. "All weekend, Lindsay kept crying, chain smoking and chewing her nails." Another alleged friend says, "She's been picturing herself in jail and she can't handle the idea of it." She may not have much time to get her head around it, either—there's a good chance she won't have to serve more than 25% of her sentence, reports the AP.
