Bauer-Griffin; Sam Sharma/Pacific Coast News While filming the Joan Jett biopic, _The Runaways_, this summer Kristen Stewart really got into character. From the rocker T-shirts to the jet

black shaggy haircut, Kristen was the spitting image of a young Jett — in fact, when the starlet and the rocker were spotted hanging out in L.A. we could hardly tell them apart! Now, Kristen

is back on set in Vancouver to shoot _Eclipse_, the third installment of _Twilight_, reviving her role as high school coed Bella Swan. Gone is Joan Jett’s mullet and back is Bella Swan’s

long luxurious mane of thick brown locks. We’re just impressed with how versatile Stewart is! But what do you think? TELL US: DO YOU LIKE KRISTEN STEWART BETTER AS BELLA SWAN OR JOAN JETT?
