Deemed as sweet and innocent young girls, Emma Watson and Selena Gomez transformed themselves into wild chicks for their new films.

British actress Emma Watson truly graduated from her goody-two-shoes image in the Harry Potter series and embraced sexier adult roles. She successfully steeled away herself on the stereotypical role as the geeky muggle Hermione Granger. However, after moving away from her sweet, innocent image, she now portrays a troubled teen doing drugs and crime.

Post-"Perks of Being a Wallflower", Emma Watson is continuing her bad-girl streak with her next movie: "Bling Ring", a Sofia Coppola-directed story of teens who burglarize celeb homes.

Emma told E! Online that she raises more hell in Bling than Perks. "I do cause a reasonable amount of trouble in [Perks]. I do Rocky Horror, I ride around on the back of trucks, I don't take any drugs in this one, so that's good. But she's a free spirit, for sure!" the actress said.

The 22-year-old British actress is now opening her doors to more grown-up roles. Reports said that the young actress is willing to take the controversial role of Anastacia Steele in the film adaptation of the erotic novel "Fifty Shades of Grey" if Ryan Gosling will play the role of Chrsistian Grey.

Selena Gomez, reeling from her fame in Disney's "Wizards of Waverly Place," is now a girl heading for a different kind of spring break in her latest film "Spring Breakers". She joined her friends Vannesa Hudgens, Ashley Benson and Rachel Korine.

Selena Gomez just got out of a controversial break up early this year with pop superstar Justin Bieber. She recently released a studio album. While Jelena fans are still devastated by the news of the couple's break up. Selena seemed to have doing a good job in moving on. The 'Spring Breakers' actress has spent the last couple of weeks in the studio working on the follow-up to 2011's When The Sun Goes Down, with reports that Selena will be dissing her ex-boyfriend in her new single.
