A source close to Britney Spears tells Us Weekly that the singer is wanting to change her style to be more like Avril Lavigne. “Britney doesn’t like her music or her image anymore,” the source explained. “She wants to get a bit moodier and punkier and sing songs with more edge, like Avril, but her record company won’t let her.” Britney is also telling pals she wants a “short and choppy” haircut, but she fears record bosses won’t let her. Boyfriend Kevin Federline is encouraging her to rebel against Jive though. “He thinks she’s old enough to do what she wants,” a source said.
