Whenever a child actor grows up, there's trouble (or at least talk of it) with going from child to adult roles. So maybe Dakota Fanning is smart to take on her sexuality before she turns 18, or even 17. Between the "Cherry Bomb" video and kissing Kristen Stewart in The Runaways, it seems nobody can believe their little Hannah Dakota Fanning is not reading American Girls Collection books between takes.
Yet we forget about Dakota's rape scene in 2007's Hounddog, which was filmed when she was 13. The only reason the kiss in The Runaways is remotely sensational is because it's with a girl, specifically Kristen Stewart. The fact that Jimmy Fallon nervously muddles through the interview did not make her look older as much as it made him look old.
