But she reckons Aussie star Chris Hemsworth might top her list.
"He's got that sparkle," she said. "You Aussies, you know how to do it! Good Aussie boy, can't really beat that."
But Stewart makes no apologies for accidentally punching her Snow White and the Huntsman co-star during an on-set fight scene.
"Before everyone gets angry at me, I felt really bad afterwards and he's being a baby about it," she's told the Seven Network. "I did not alter his face in any way. We were both so into the scene at that moment ... and you know, it made it into the movie.
"I think it looks really good, couldn't have faked that."
The starlet said she had her Australian mum, director Jules Mann-Stewart, to thank for getting into the film business.
"I wanted to start doing this because of my family, I've always looked up to them," she said.
She said filming Snow White and the Huntsman was physically gruelling.
"I put myself through it absolutely. It's one of the things I was most excited about, I knew that me and Chris and Charlize (Theron) were going to be dropped into this world of absolute make-believe, We didn't have to fake it."
Stewart walked the red carpet with Hemsworth in Sydney on Tuesday night for the opening of their new action-adventure epic, which provides an interesting twist on the much loved fairytale.
