Kristen Stewart ‘So Proud’ Of ‘New Moon’ Cast

With the success of "Twilight," Kristen Stewart knew she'd be back for the sequels – but she told Access Hollywood on Sunday that she's glad to have company.

"We're so proud of [Taylor Lautner]," she said at the junket for her latest film, "Adventureland." "It's been a year since we shot the last one and he's been working on it the entire time. Not just physically — he's gotten buff and everything but he's [also] so [into] it."

Taylor, who played Jacob in "Twilight," earned the role again for "New Moon" after putting on over two dozen pounds of muscle to play the character as he grows into a large werewolf in the sequel.

And "New Moon" will feature new additions as well — Dakota Fanning has joined the cast of the film, news which Kristen thinks is "awesome."

"It's cool to have small characters be really vivid and have them stick out," she said. "I feel like she'll do something really interesting with it. It's a crazy character she plays."
