Chipped nails are out. Bashed nails are in.

Lindsay Lohan may have thought she was hot stuff when she got a "chipped manicure" to give her a rocker-girl chic look, but Sienna Miller is taking this season's black nail trend to a new level. The Factory Girl actress was spotted with a bashed black thumb at New York's JFK airport when she was yapping in the customs area (where cell phones are banned) about her bleeding thumb. Could the trendsetting Brit manage to bring back self-mutilation?
