Child stars all grown up: Selena Gomez – "Spring Breakers" is quite a departure for Selena Gomez, who started her career on "Barney & Friends." The actress later made a name for herself in Disney's "Wizards of Waverly Place" and family-friendly Disney flicks such as "Another Cinderella Story." Gomez has shown she's growing up by taking on more mature projects like her Funny or Die video, "Fifty Shades of Blue." Even her red carpet fashion choices and relationship with Justin Bieber, which ended earlier this year, separate the actress from her Disney persona.
Vanessa Hudgens – In 2006, Vanessa Hudgens shot to fame with Disney's wholesome TV movie "High School Musical." The actress, who next appears in the racy "Spring Breakers," didn't just alter her angelic image by appearing in projects such as 2011's "Sucker Punch." Nude photos of Hudgens leaked online in 2007 and 2009.
Zac Efron – Like his "High School Musical" costar and former girlfriend, Vanessa Hudgens, Zac Efron has broken out of his Disney shell with roles in flicks like "The Lucky One" and "New Year's Eve," in which he spends quality time with an older woman played by Michelle Pfeiffer. "The Paperboy" marks Efron's most adult role due to the film's infamous urination scene between the actor's Jack Jansen and Nicole Kidman's Charlotte Bless.
Daniel Radcliffe – Daniel Radcliffe distanced himself from "Harry Potter" when he starred as Alan Strang in the 2007 revival of "Equus." Radcliffe, who appeared in a nude scene onstage, received positive reviews for his grown-up performance.
Miley Cyrus – Miley Cyrus and her TV alter ego Hannah Montana became household names thanks to her popular Disney show, which ran from 2006 to 2011. Photographer Annie Leibovitz captured Cyrus, 15, wrapped up in a sheet for Vanity Fair. Cyrus' pole dancing performance at the 2009 Teen Choice Awards also caused a stir, and she was berated for giving producer Adam Shankman a lap dance in 2010. The same year, a video surfaced of the singer smoking a bong filled with salvia, an herb that's legally sold in many health food stores.
Shia LaBeouf – Another former Disney star, Shia LaBeouf has come a long way from "Even Stevens." Films like "Transformers," "Wall Street: Money Never Sleeps" and "Lawless" show the actor in more mature roles. And in 2012, LaBeouf bared it all -- and we mean all of it -- in a Sigur Ros music video. He'll soon star in Lars Von Trier's "Nymphomaniac," which will likely be LaBeouf's most adult role to date.
Dustin diamond – After playing Screech Powers in "Saved by the Bell" for 12 years, Dustin Diamond directed and starred in a sex tape called "Screeched." He's since appeared as himself on reality TV shows like "Celebrity Fit Club."
Christina Aguilera – Former Mouseketeer Christina Aguilera has made headlines since she came on the music scene in 1999 with her self-titled album. But by the time she released "Stripped" in 2002, Aguilera was on a whole other playing field. (Remember picking your jaw up off the floor after watching her "Dirrty" music video on "Total Request Live?")
Britney Spears – Just like Christina Aguilera, Britney Spears went from "The Mickey Mouse Club" to being "not that innocent." After becoming a mom, the singer shaved her head and checked into a treatment facility in 2007. She's since released three albums and appeared as a judge on "The X Factor."
Demi Lovato – Like Selena Gomez, Demi Lovato got her start on "Barney & Friends" before landing her own Disney show, "Sonny with a Chance." In 2010, the actress and singer opened up about her "emotional and physical issues." She eventually checked into an inpatient treatment center. Along with Spears, Lovato judged the second season of "The X Factor."
Drew Barrymore – Aside from a problem with substance abuse early on in career, Drew Barrymore successfully made the transition from child star to revered actress-producer-director. The "E.T. the Extra-Terrestrial" actress was in rehab by age 13; however, she was back on track around age 20.
Justin Bieber – Having been a household name since the ripe old age of 15, Justin Bieber has grown up in the public eye. At 19, the singer is apparently showing us his grown-up side, which includes hitting the London club scene, showing up late to a concert, smoking marijuana -- and then apologizing for it on "Saturday Night Live."
