Another day, another slew of rumors about who will get the plum lead roles in the upcoming film adaption of '50 Shades of Grey.' This time? It's Dakota Johnson, whom you may remember from a notable scene with Justin Timberlake in 'The Social Network.'

The 23-year-old former model -- who's the daughter of 'Miami Vice' star Don Johnson and actress Melanie Griffith -- is the latest actress getting buzz to step into the submissive shoes of Anastasia Steele in the movie version of the novel that took the world by storm in 2011.

While Johnson recently starred in the short-lived FOX sitcom 'Ben and Kate' and had supporting roles in '21 Jump Street' and 'The Five-Year Engagement,' she's probably best known as "that girl Justin Timberlake slept with in 'The Social Network.'" But according to insiders, not being a household name would actually work in her favor to snag the Anastasia role.

"By all accounts, the part ... is a potential star-maker, which means there's limited upside for an established star," reports TheWrap, adding that "the chosen actress will have to be comfortable with onscreen nudity and kinky sex," and that as a former model, "Johnson [is] already comfortable flaunting her body for the camera."

No word yet on who will actually get the role -- or that of leading man Christian Grey -- but decisions will have to be made soon, since the film is expected to hit theaters in August of next year.
