Kristen Stewart's hair is orange! Shocking Twilight fans on April 4, the New Orleans salon Maison de Cheveux posted a picture on Instagram of Bella Swan with cantaloupe-colored locks.

But don't worry. The new hue may not be here for long. It's for Stewart's role in the film American Ultra, where she teams up again with Jesse Eisenberg. 

Though Stewart is best known for her role in the vampire saga Twilight, she and Eisenberg also had a cult following after their romantic comedy Adventureland. And we couldn't be more excited that they're joining forces again.

Jesse Eisenberg and Kristen Stewart in 'Adventureland' When Kristen Stewart appeared in the romantic comedy 'Adventureland' in 2009 her hair wasn't as dark as Bella Swan's. But it was far from her current orange 'do.

American Ultra, which will be filming in New Orleans between April 14 and June 10, traces the story of a stoner living with his girlfriend (Kristen Stewart) in a small town.

"Simply put, 'American Ultra' will be the most fun you can possibly have in a movie theater without the use of drugs, fireworks or canola oil," producer Anthony Bregman said.

Most Twihards think of Bella Swan as a brooding brunette. But the 23-year-old stunner was actually born a blonde. One of Stewart's first roles was in Panic Room (2002) playing Jodie Foster's daughter. And the resemblance between the two actresses was uncanny at the time.

Stewart's film In The Land of Women was quickly forgotten after it hit theaters in 2007. But at the time Stewart was hailed as the next big thing in Hollywood. Starring as Meg Ryan's daughter who is lusting after Adam Brody's character, Stewart's character looks far different than Bella.

But, of course, it was her role as Robert Pattinson's girlfriend in Twilight that is most remembered. During filming, Stewart truly transformed into her alter ego. She took on a Goth look both on-screen and off.

Her look off-screen was a mix of tomboy and punk, which often garnered mixed reviews.

Some Twihards say Stewart may be trying to shed her Twlight persona with a new look. Though she met the love of her life on set, the relationship ended with much heartbreak after she admitted to cheating with Snow White and the Huntsman director Rupert Sanders.
