KRISTEN STEWART BECOMES LEFT-HANDED FOR JETT PORTRAYAL

Twilight star Kristen Stewart went all out to portray rocker Joan Jett in the new Runaways biopic - even becoming left handed.

The young actress spent time with Jett, who was a consultant on the film about her famous girl band, and studied the rocker.

Impressed Jett says, "I'm a lefty too - not guitar wise - but in my handwriting and so she switched that up too; she started writing left handed."
