Six degrees of Jake Gyllenhaal!

Kristen Stewart has a major girl-crush on one of Jake Gyllenhaal's former flames: No, not Taylor Swift, Reese Witherspoon, Kirsten Dunst or Natalie Portman, but Jenny Lewis, Gyllenhaal's surprise date at Sunday's Golden Globes.

Stewart, 21, tells the February issue of Vogue that she's a huge fan of musician Lewis, 35, who fronts the beloved indie band Rilo Kiley and has released two acclaimed solo albums.

"She's the only person I've ever met that I can't function around." the Twilight star gushes of former child actress Lewis, who dated Gyllenhaal, 30, in 2001.

One special person Stewart refused to dish about? Real-life love Robert Pattinson. "It's not my job," she retorted when asked by Vogue.

Instead, the actress got choked up talking about filming On the Road, based on Jack Kerouac's classic book that inspired the "Beat" movement — a world away from the Twilight mega-franchise that made her rich and famous. Playing first wife of Beat icon Neal Cassady, Stewart says was "crying my head off" shooting the film. "I didn't want to leave."

Reuniting with Pattinson and her Twilight castmates for Breaking Dawn in Baton Rouge felt "like going back to school," the star complains. "Twilight is a different beast."

Not that she begrudges the series' incredible success.

Her character Bella Swan is "embedded in so many people's psyches at this point. It's starting to enter my head a lot more than it used to because it's at the end and it's come such a long way. I just want the fans of the book to be happy."

Plus, there's her massive paychecks. "It's funny when you are endowed not only with public recognition on a f***ing seriously vast level, but also money," says the star, reportedly paid $25 million plus a percentage of grosses for the two Breaking Dawn films. "Like, funds."

What about film critics? "I don't necessarily care about anyone else," Stewart says, laughing.

But worldwide fame has its costs, of course. "There's no way to eloquently put this: I just can't go to the mall. It bothers me that I can't be outside very often. And also to not ever be just 'some girl' again. Just being some chick at some place, that's gone," Stewart admits.
