MTV interviewed Kristen Stewart about Taylor Lautner and Chris Weitz!

Another concern in Stewart’s mind over the past few weeks had been which actor will play the pivotal role of Jacob Black — and whether she and this mystery man would be able to establish the same sort of chemistry that she had with Robert Pattinson in “Twilight.” Now that Taylor Lautner has been re-cast in the role, however, she’s convinced that they can make it work.

“Yeah, absolutely,” Stewart said. “I’m so glad they didn’t have to find somebody else; we already had him! I didn’t understand all the deliberation on [whether to bring him back]. But now that it’s set, we can all rest.

“He’s really buff!” she exclaimed of Lautner, who’s packed on nearly 30 pounds of muscle so far to prepare for Jacob’s werewolf growth spurt. “He definitely is. It took him a lot of time.”
