Villa/WireImage Twilight News 01 of 06 Kristen Stewart Channels Joan Jett BauerGriffin; Michael Ochs Archives/Getty Images It's only been a couple of weeks since shooting wrapped on New Moon, but Kristen Stewart has already undergone a dramatic transformation in preparation for her next role. The actress has been spotted at rehearsals for her new flick The Runaways-the story of the iconic '70s all-girl rockband-with much shorter and darker-colored locks. She's been keeping the new 'do under wraps in either in a pony tail or tucked under a hoodie, but since she's playing Joan Jett in the flick, it's safe to say we'll be seeing her out-and-about soon with the music icon's signature shag.

Sasha Eisenman; Courtesy of Summit Entertainment; Thomas Haas Want to make something special for your favorite Twilight fan's birthday? Whip up a cake just like the one seen in the New Moon trailer. Sure, there was some movie magic involved (the actual "cake" was fake), but the striped icing effect was the edible creation of confectioner Thomas Haas, owner of Thomas Haas Fine Chocolates in Vancouver. Haas' wife Lisa walked us through the how-tos of recreating the confection:1. Cover each cake tier with a "mask" of white fondant amp#91;a thick, malleable icingamp#93;. Stack tiers from largest to smallest.2. Separate one package of fondant into 5 batches. Use food coloring to tint each batch a different shade of green.3. Roll each batch of fondant into a thin sheet and cut into strips of varying width.4. Attach the strips around each tier using stiff royal icing as glue.5. Place red, yellow and green Gerbera daisies around the bottom of each tier. amp#149; More Secrets From the Setamp#149; More New Moon News -Bronwyn Barnes Add to Facebook | Add to Twitter 03 of 06 Kristen Stewart Steals Bella's Style Lisa O'Connor/Zuma; Courtesy of Converse Kristen Stewart took a break from the Italian set of New Moon to attend the MTV Movie Awards, but she didn't leave her character's comfy-casual style far behind. While she looked stunning in a red Yigal Azrouel dress, she made a statement by pairing it with a pair of Converse sneakers. JustJared.com has reported it was a last minute replacement for pumps after she twisted her ankle, a trick she must have picked up from her Twilight character, Bella. In the film Bella injures her leg before prom and accessorizes her dress with a walking cast and Converse sneaks.

Preparation. "We fitted her way in advance because of her hectic New Moon schedule," says Greene's stylist Ilaria Urbinati, who styled her for MTV Movie Awards. "We had to alter the dress," she said of the originally straight-cut Dolce amp Gabbana dress. After accessorizing with a neon clutch and a dash of vintage beauty, Greene was red-carpet ready just 24 hours after arriving from Italy. "The dress felt very old school, that's where the idea for the hair and jewelry came from," said Urbanati. "The neon clutch gave it a little edge."

Villa/WireImage The hunky Twilight vampire has been bitten by a sharp-toothed trend: On a recent photo shoot, the actor spotted a shark tooth necklace and asked where he could buy one. "We sent over some pieces [for the shoot], but we knew that Robert didn't wear much bling," says Finn Jewelry's Candace Pool, who tells us the designer of the incisor "freaked out when she heard how much he liked the necklace." Pattinson opted for the 18-carat gold charm on a leather cord-the same style owned by Brad Pitt and Liev Schreiber.
