With the announcement that Taylor Lautner is returning to the Twilight sequel, New Moon, more rumors have been ablaze.

The biggest rumor surrounds High School Musical star Vanessa Hudgens, who reported auditioned for the role of a werewolf named Leah Clearwater in upcoming flick New Moon.

Not only does her agent deny the claims, but Summit Entertainment, who produced Twilight and is producing New Moon, has officially denied that Hudgens has been cast.

Lautner, however, has reportedly put on nearly 30 pounds of muscle for his role in New Moon. The 16-year-old actor said he bulked up with two-hour gym sessions for seven days a week and ate as much as he could.

Twilight star Robert Pattinson also recently made the news, reportedly getting in trouble with the film executives for cutting his hair, which is an essential part of his character, Edward Cullen.

New Moon, with new director Chris Weitz on board, starts filming in spring 2009 and is slated for a November 20th, 2009 theatrical release.
