The 16-year-old actress admits she has fancied the hunky star, 33, since he wrapped his arms around her once in the past to give her a cuddle.
She explained: "He once gave me a hug. It was pretty intense because he's dreamy. I have a Ryan Gosling colouring book so whenever I want, I can colour Ryan."
The blonde beauty - who is the younger sister of Dakota Fanning, 20 - will next appear in the upcoming movie 'Maleficent', alongside Angelina Jolie, but she admits she was initially scared of the 38-year-old beauty.
She explained to Fashion Magazine: "She is the most elegant lady in the entire world. When she walks into the room, everyone looks and notices... she has such presence and she's really that powerful. No one else could play [the leading role] Maleficent. I was nervous to meet her at first... she's like the queen. When I met her during rehearsals and she immediately grabbed me and hugged me and then I was fine."
Meanwhile, Elle, who is still studying at school, believes Hollywood puts a lot of pressure on young people to grow up and throw themselves into their careers.
She said: "That condescending thing gets me. The 'you're young now but you'll know in a couple of years what life is about', kind of thing. I don't think in a couple of years I'm going to have this huge revelation. I'm still going to be the same person. When you are an adult not everything changes. Teens are who they are. Trying to change us to be older before we should doesn't make sense. I always want to have a free spirit--I don't want to be strict with life."
