Hermione is fuming mad about the "Fifty Shades of Grey" rumor that just won't die.

Weeks after insisting that she was not going to star in the upcoming film adaptation of the very erotic bestseller, Emma Watson took to Twitter again over the weekend to slam Anonymous after the "hacktivist" group posted alleged top-secret studio documents purporting to link the "Harry Potter" alum with the big-screen "Fifty Shades of Grey."

Watson tweeted:

Late last week, Anonymous hacked into German Studio Constantin Film, lifting internal documents and email addresses. Some documents revealed a list of films that were in development -- mostly already known to the public -- and some the company was thinking about acquiring. One such memo stated that Watson was attached to star in Focus Features' "Fifty" adaptation.

That prompted Watson to yet again shoot down the persistent rumor that she'd play Anastasia Steele in "Fifty" -- which originated as a piece of "Twilight" fan fiction.

Now that we know what Watson won't do, it's time to talk about all the buzz she's getting for the things she will do. After her well-received turn in 2012's "The Perks of Being a Wallflower," the 22-year-old actress is looking to make a splash in Sofia Coppola's "The Bling Ring."

Hitting theaters this June, the film features a tatted-up, daisy duke-sporting Watson in the fictionalized story of a posse of Southern California teens who became infamous for burglarizing celebrity homes, including those of Orlando Bloom, Lindsay Lohan, Megan Fox, and Paris Hilton.

But Watson has made it clear. She's not the lead (as the new trailer for "Bling" would lead you to believe):

Back to "Fifty," the 22-year-old actress is not the first star speculated for the film adaptation's steamy leading role. Mila Kunis denied rumors she was cast as Steele, joking earlier this month, "This 'Fifty Shades Of Grey' thing is just not going to leave is it!" Nina Dobrev, Shailene Woodley and Emma Roberts have also been mentioned in the "Fifty" casting rumor mill.

Ryan Gosling has often been listed as a fan favorite to take on the sexy yet troubled male lead as Christian Grey. Other actors rumored for the role include Matt Bomer, Ian Somerhalder and Henry Cavill. (Superman, really!?)

"Fifty" screenwriter Kelly Marcel (television's "Terra Nova," 2011) revealed in January the movie could easily nab a NC-17 rating, which would officially classify it as porn. "It's going to be raunchy," she told the Sunday Times (U.K.).

We'll just assume Watson doesn't do raunch.
