Speaking to MTV, Stewart joked that she was partly responsible for the actors' rise to fame as Edward Cullen and Jacob Black in the vampire drama.
"I take credit for both of these guys actually, fully and completely," she said.
Lautner also revealed that he had no real idea of the material when he auditioned for Twilight.
"It was just so generic. It just felt like any other audition," he explained.
"I had no idea what Twilight was. I asked people. I said, 'What is this thing?' They said, 'There's vampires, and you're in a forest'. That's really all I heard about it."
Breaking Dawn - Part 2, the final film in the Twilight movie saga, will open in cinemas on November 16.
