Wack-o'-Lantern: Don't panic, people. Despite the telltale Troll doll hair transplant, that's Mischa Barton, not Lindsay Lohan, although they do seem to have an alarming number of things in common. Like Lindsay, Mischa has suffered severe personal and professional setbacks in recent years (e.g., DUI, rehab, the two-episode train wreck that was "The Beautiful Life"). And, like Lindsay, Mischa loves fashion, even though it rarely loves her back. Mischa should heed the cautionary tale of her jailbird peer and get her act together, which means no more coif touch-ups using Kraft Macaroni & Cheese, and no more photo ops wearing an itchy, inflamed cut-out bikini monstrosity in need of a hefty dose of penicillin.
