Kristen Stewart hat film car shots reading

We'd recognize this grunge goddess anywhere!

On Wednesday evening Kristen Stewart left after a long day on the set of Still Alice in New York City, and the 23-year-old actress hid in the backseat of her chauffeured vehicle. K. Stew was clutching a copy of the novel of the same name by Lisa Genova ... we're hoping this is the second time she's reading the book!

The big screen adaptation of Genova's novel is about a psychologist who discovers that she’s suffering from early onset Alzheimer’s disease, and it stars Kate Bosworth, Alec Baldwin and Julianne Moore. The film is set to be released in 2015.
