Selena Gomez, Vanessa Hudgens and Ashley Benson look like they couldn’t be having much more fun filming their new movie “Spring Breakers.”

The trio of young Hollywood stars and a slew of extras have been shooting party scenes almost everyday in the skimpiest bikinis.

Gomez, a straight-laced former Disney star, has been pictured downing alcohol and dancing in public half naked. Selena, 19, is apparently enjoying the adventure.

She posted photos on Twitter of herself and Benson. They were posing on a police car from the movie.

“Lol I’m so lame. Having way too much getting arrested,” Selena Tweeted.

Gomez has shown more flesh in the movie than even her racy South American concert tour. She’s been photographed in tiny bikinis and short shorts. The extras are even hotter, and some in the movie went topless.

The party scene seems to have shifted to the street. Barely dressed girls from a crowd scene while Selena, Ashley, Vanessa and Rachel Korine cavort in the crowd. They have been on location in St. Petersburg, Fla. for several weeks.

“There’s a bit of craziness inside of me as well, so I’m excited to let loose,” said Hudgens, who plays the lead character, Candy.

“She’s a crazy party girl. She’s the one I feel kind of gets everyone going and pushes everyone a little bit. It’s all done in the craziest manic way,” she told E! News.

James Franco was in Florida this week to film scenes in the movie. He plays a shady drug dealer who gets mixed up with the girls, who robbed a bank to finance their spring break vacation.
