Kristen Stewart Dyed Hair For New Movie

Kristen Stewart caused a stir today when we saw her with new copper coloured locks and now the actress has revealed why she's ditched her old look.

KStew told MTV News that her new look is for her next movie, which is based on the Jack Kerouac novel, On The Road.

She said: "It's kind of blond right now. Like, reddish brown. I'm doing it for 'On the Road.’”

Kristen is playing the part of Marylou and will star alongside Garrett Hedlund who is playing the lead role of Dean Moriaty.

Of her new co-star, Kristen said: “I've met him a bunch of times, and I've hung out with him twice.

"He's a great guy. He's super into it… He's, like, so in character, and he's driving to Montreal. He's awesome. I'm really, really excited.”

Will we see sparks fly as they did between Kristen and Robert Pattinson on the set of the Twilight Saga?!
