In between filming 'New Moon' and 'Eclipse,' star Kristen Stewart cut her hair to play rocker Joan Jett in the bio pic 'The Runaways.' But the mullet Stewart currently has obviously won't work for her role as Bella Swan. So producers put her in a wig to film the third movie. And from the looks of it, it's the same hair piece worn by Taylor Lautner -- who plays Bella' best bud Jacob -- in 'Twilight.' We know the franchise isn't strapped for cash, so skimping on wigs shouldn't be a concern.
