Ellen, a 20-year-old Canadian actress, says she fell madly in love with Diablo Cody's script the first time she read it. "[I thought], 'I have to do this,'" she says.
Despite her skyrocket to fame, Ellen remains humble about her success. "I'm sitting next to Oprah right now on a couch," she says. "I'm just so grateful to be in the film in the first place. ... It's a huge gift."
