As art-house films go, Spring Breakers has bucket loads more Britney Spears music than usual. Read director Harmony Korine telling us about listening to "Everytime" 500 times here. "Baby One More Time" also plays a big part earlier in the film. Well, at their SXSW panel, the moderator convinced the film's stars Selena Gomez, Ashley Benson, and Rachel Korine (Vanessa Hudgens missed it because of the flu) to karaoke it a little bit. They're hesitant at first, but they eventually sing along — spring break!
