Why Did Britney Tell All To Star?

Starmagazine.com has a preview from their cover story on Britney Spears that has the gossip world buzzing. Why did Spears not only not sue the tabloid for their alleged cocaine use story about her, but then give a tell-all interview with the tabloid when much more respectable and high-profile mag’s would have killed for a story on the shocking revelations? Does Star magazine have career threatening dirt on the singer (photos/videos/documents), forcing her to do an interview with them in exchange for their silence?
