Britney Spears collaborator Nate "Danja" Hills has revealed the singer hasn't let any of her personal life into her new LP. Hills – a pal of producer Timbaland – talked to US music station VH1 about the pop diva's forthcoming album. "There was no, 'I need to let it all out'," Hills said. "She said she deals with that in another way." Having written eight songs together, Hills says Spears wants to make an album that's fun, has a hip-hop flavour and is danceable. The subject matter, he said, is up-tempo and private. "It's fun, it's basic and there's nothing wrong with that. It's about feeling good, celebrating womanhood. And if you don't dance to it, I really don't know what you're listening to." Expect the first single in September.
