Britney Spears writes song about paparazzi

Sounds like Britney Spears has had enough and is ready to fight back - at least through her upcoming album.

"She wrote a song with me that's kind of introspective about how people and the paparazzi are constantly following her around," reports the latest "It" megaproducer, J.R. Rotem, who's been in the studio almost daily with Spears, who is expecting her second child.

Just as an innocent bystander, Rotem says the media frenzy that follows Spears "is annoying. Their life is crazy. I'm also working with K-Fed, her husband, quite a bit on some hip-hop stuff, and literally every time he comes over, he's followed by, like, five to eight paparazzi trucks. They just camp out in front of my place while we work and try to take pictures of anything. They cannot go anywhere without being followed. It's amazing and very aggravating."

The classically trained pianist — who's masterminded some 60 hit tunes in the last year alone for the likes of Mya, Busta Rhymes, Talib Kweli and Rihanna, whose single, "S.O.S. (Rescue Me)" just rocketed to No. 1 on the Billboard singles chart — says he and Spears are "working on about three or four different songs at the same time." He adds, "She's definitely touching on subjects that have to do with her everyday life — being married and having a baby and what her life is now — that will be reflected in the album, but it's going to be a combination. Britney's the queen of pop, and she's not going to go off on some weird tangent. We're also doing the club kind of stuff, that's very pop, dance with hip-hop. It's like next-level Britney. Her fans are not going to be disappointed."
