Bieber's good girl gone bad!

Selena Gomez is set to tweak her sweet, innocent persona with Spring Breakers, a raucous, racy flick about law-breaking, alcohol-swigging coeds directed by controversial Kids scribe Harmony Korine and costarring Vanessa Hudgens and Rachel Korine.

The "Love You Like a Love Song" singer, 19, shared shots from filming -- and run-ins with the law! -- via Twitter and Instagram on Friday.

"Spring break- busted," Gomez captioned one photo, which shows Justin Bieber's love in an open robe and skimpy bikini alongside Korine, as both lean nonchalantly against a police car. Another shot, this one black-and-white, shows Gomez sitting in the back seat of the vehicle.

"Lol I'm so lame," she wrote. "Having way too much [fun] getting arrested"

In Spring Breakers, Gomez and company play young women who commit robbery in the hopes of funding their spring break trip -- then they fall in with a drug dealer, who tries to recruit them into his line of work.

Paparazzi shots of the shoot revealed Gomez, Hudgens, Korine and other stars drinking Jack Daniels (straight out of the bottle!) and partying in the wee hours down in Florida -- all in front of the movie cameras, of course.

But the Spring Breakers experience hasn't been 100 percent fun 24/7 for Gomez. On March 12, she admitted on Twitter she got a case of nervs. "Got bad anxiety after shooting.. I need to relax."
