Dakota’s only 17, but she looks pretty grown-up in this new fragrance ad.

While some teen starlets like Taylor Momsen and Miley Cyrus get dissed for their skimpy clothes and wild behavior, Dakota Fanning has managed to hold on to her “good girl” image. All that may change when her fans get a look at this ad for the new Marc Jacobs fragrance “Oh Lola,” which features the 17-year-old posed with a large perfume bottle between her legs. Despite her squeaky clean image, Dakota hasn’t shied away from racy roles, like playing drug-addicted rocker Cherie Currie in “The Runaways” when she was just 15. She may not be a wild child, but Dakota’s definitely growing up fast!
