Goodbye Hermione Granger, hello Bad Girl!

Actress Emma Watson had heads turning with her new rebellious look on the set of The Bling Ring. The 22-year-old actress flaunted a tramp stamp tattoo, a bralette top, denim shorts and stiletto heels while filming scenes in Venice Beach.

Emma Watson's tramp stamp tattoo garnered the most attention, as many fans debated whether the ink was real or not.

Watson was photographed baring a large and ornate lower-back tattoo, with orange and red flames. Fans worried that the Harry Potter star had gone and inked herself for real. Emma Watson was hot until she got this tattoo - #Trampstamp, tweeted Twitter user Jake Graham. Emma Watson has a 'tramp stamp' tattoo, AND she's showing off her bra? posted Twitter user Holy Moly!

Fret not, Emma Watson fans. The young actress' tramp stamp is nothing but a temporary tattoo for her role as Nicki in The Bling Ring.

The Bling Ring was a group of tech-savvy youngsters from Calabasas, Calif., who robbed the homes of mega-celebrities like Megan Fox, Paris Hilton, Orlando Bloom, Rachel Bilson, Lindsay Lohan and Ashley Tisdale between 2008 and 2009, according to the Daily Mail. The film is directed by Sofia Coppola.

Emma Watson's Nicki is a California bad girl whose mother, an ex-Playboy model played by Leslie Mann, pushes her and her sister to find fame. Nicki proceeds to burglarize celebrity homes with her group of friends, pawning the stolen designer items on the Venice boardwalk. 

The actress had to transform her look almost completely for the role. The typically demurely-styled starlet has been donning skimpier, racier outfits for the role of Nicki. Gone is her cute pixie cut, having been replaced by long brunette extensions. Denim shorts, stiletto heels, crop tops, short skirts and skin-tight pants make for a risqué look, while the tramp stamp emphasizes her bad-girl image.

Watson seems to be enjoying filming the new flick. Filming Bling Ring is going great. As Israel would say 'we are slaying this!'. Thanks for the good luck messages, she tweeted to fans last week.

Over the weekend, the starlet attened the Coachella Music and Arts Festival in California and was spotted kissing new beau, Will Adamowicz. The couple met while attending Oxford University.
