In the face of growing rumors that he will be replaced -- perhaps by Michael Copon -- in the Twilight sequel, Taylor Lautner has bulked up and is fighting back to reprise his role as Jacob Black. He tells MTV that he has put on 19 pounds and will put on ten more to fill out the werewolf role in New Moon. Noting that he hasn't been scratched off the list yet, Lautner is optimistic about his sit-down with director Chris Weitz this Friday to talk it over. And the fans appear to be in his corner on this one, with an MTV poll showing him a 12-1 favorite over all other contenders for the role, including Copon. Given Weitz's evident eagerness to appease the fan base, it looks like he may still have a fighting chance.
