Anne Hathaway rocked out to some tunes thanks to her fancy headphones on a walk around LA yesterday. She's opened up about her favorite artists [1] in the past, but apparently Miss Hathaway is also something of a singer herself. Last night she and her Devil Wears Prada [2] costar, Emily Blunt, sang backup [3] for the band at the Green Door after a long night of partying. Sounds like Anne has no problem finding ways to unwind after her long days of acting and making fancy commercials for Lancôme [4].
