NEW YORK — It's practically become a rite of passage for teen pop stars — if you want to cross over to the big screen, it might help to channel a little Joan Jett. That's what Britney Spears did in "Crossroads," when she sang along to "I Love Rock 'N Roll," and now JoJo follows suit, in her upcoming film debut, "R.V."
"I made a conscious decision not to play a singer in a movie, so I'm definitely not [singing for real]," she said. "But in one of the scenes, I have to put on an iPod and just sing very off-key to a song I had no idea existed before, a song by Joan Jett. It's so out of character for me!"
