Kristen Stewart's a killer cook, says co-star

Rachael Ray might have some unlikely competition in "The Twilight Saga's" Kristen Stewart. According to Garrett Hedlund, Stewart's co-star in the upcoming "On the Road," the actress has some killer culinary skills.

"You got to try the tortilla soup!" 26-year-old Hedlund, who currently appears in "Country Strong," tells MTV. "It's incredible. She's honed it."

Stewart herself boasted about the dish in an October interview with MTV, saying that she had done a lot of cooking for the "On the Road" cast.

"I didn't bake; I cooked a lot, though. I was the only girl on set," she said. "I think I can do a really, really good, terrific tortilla soup. That was my 'On the Road' dish."

Still, Stewart, 20 admits that she's uncomfortable with her reputation as a kitchen whiz.

"I get really embarrassed when people ask me what I cook, for some reason," says the star, who once whipped up a six-hour marinara sauce for a dinner party for the "Twilight" gang. "I shouldn't say that I cook anymore."
