Word is that she wasn't the easiest person to speak to about her much-hyped vampire flick.

Socialite Life reports that Stewart had problems with answering basic questions about her film, and was quoted as saying ''I really, really hate doing this" during the press junket.

It might have had something to do with her photographed fondness for smoking something out of pipes.

That could make a person hazy. Hey, at least she's satisfying the munchies at the salad bar and not the potato chip aisle.
