Britney Spears will use her new album to lash out on those who have wronged her, according to a new report.

The Toxic hitmaker will be putting the finishing touches to the album, the follow-up to 2007's 'Blackout', over the summer; and Britain's Sunday Mirror newspaper claims that in one song, titled 'ATM', Britney accuses her mother of using her for money. It contains the lyrics: "Hey Mama, I know it's my cash you seek... You know they treat me like an ATM, but y'all know that I'm too good for 'em."

Another song, titled 'Already Bad', takes aim at her relationship with Justin Timberlake, dismissing her teenage claims that she would not have sex before marriage - and suggesting she wasn’t even a virgin when they started dating. "I know you thought you were the first, but I had already quenched my thirst, I was already bad," the song reveals.

A source told the paper, "The songs are up tempo and there are some wicked heavy beats. She's built on the foundations she laid in her last album, Blackout.

"These tunes will change the way people think about Britney. A lot of people have messed her around over the years and she’s bottled up all this anger and now she’s just let it all out."
