Charli XCX, the rising British pop star who co-wrote Icona Pop's "I Love It," is apparently working on new music for none other than Britney Spears. "Who knows how it will go," she told Digital Spy. "We've written one song and it's a great track and if she likes it then amazing." Not that she needs any more people bossing her around, but: Like it, Britney! Use it! This could be great.
