JUSTIN BIEBER's on/off girlfriend SELENA GOMEZ has urged parents not to let her young fans see her new movie SPRING BREAKERS - because it's a bit too racy for them.

The former Disney sweetheart is one of four college girls who are forced to work for a drug and arms dealer when he bails them out of jail after they're accused of robbing a restaurant in order to fund their spring break vacation.

She explains, "I've done my best to warn the parents and my younger fans. I'll be 21 this year, so, for me, it's been kind of refreshing and nice to step out of my comfort zone and do things that I didn't think I could do as an actress... But 18 and older (fans), go see Spring Breakers!"
