Lindsay Lohan is trying to make light of her situation as jail looms. "The only 'bookings' that i'm familiar with are Disney Films, never thought that i'd be 'booking' into Jail... eeeks," the actress tweeted. Her ex-girlfriend and supporter Samantha Ronson responded, "well- you haven't lost your sense of humour." Lohan will appear at a hearing in Beverly Hills Tuesday to surrender for a 90-day jail sentence for violating the rules of her probation stemming from a DUI charge. She’s plowed through several lawyers, including Robert Shapiro, who, after a different lawyer quit, was unofficially representing Lohan but is officially no longer doing so. Due to jail overcrowding, the troubled star is unlikely to serve much more than a small fraction of her sentence.
