Fifty Shades Of Grey Cast Dakota Johnson Goes Back To Her ‘Roots;’ Stunning In New Movie Still

"Fifty Shades of Grey" cast Dakota Johnson went back to her roots as a natural blonde as she attended the Stella McCartney Green Carpet Collection on Sunday evening. The 24-year-old model also looked stunning in the latest movie still.

According to MailOnline, "Fifty Shades of Grey" cast Dakota Johnson dyed her hair dark brown to take on the persona of Anastasia Steele, but when she attended the fashion designer's event, she was already back to her natural locks.

Dakota Johnson also wore a white dress with a frilly skirt to the event which she paired with nude heels, the British tabloid said.

The official Twitter of the production posted a photo of Dakota Johnson putting a pencil on her lips as she seems to be looking up, presumably at Christian Grey, while she takes notes. The black pencil also has a golden "Grey" emblazoned across it.

The pic was simply captioned: "Happy Birthday, Anastasia. #FiftyShades."

After publishing the social media photo, Us Weekly magazine can only comment: "Damn, Dakota!"

"Johnson is shown as the protagonist, with her brunette locks framing her face and bangs skimming her eyebrows. She holds a black sharpened pencil bearing the name Grey between her fingers, ever-so-suggestively resting the eraser on her bottom lip," the magazine said.

Earlier, it was reported that "Fifty Shades of Grey" cast Dakota Johnson has banned her mother, Melanie Griffith, from watching the film.

In its "Fifty Shades of Grey" news update, IndieWire asked Melanie Griffith if she's excited to see the film, but the "Body Double" star is not going.

"[Dakota] was like, 'You guys cannot come. There's no way.' So we're not going," she said.

Earlier "Fifty Shades of Grey" news reports also revealed that "Miami Vice" star Don Johnson also won't see the film, and it's not because of the sex scenes but because he has no interest in that kind of movie.
