Britney Spears is using her new album to get revenge on the people once closest to her-and mother Lynne Spears and ex-boyfriend Justin Timberlake have emerged as Public Enemies Nos. One and Two.

“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,” a inside source told the Sunday Daily Mirror.

According to the spy, Britney has already penned a number of diss tracks, including one entitled “ATM,” which accuses her mother of using her for money.

The song includes 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 single, dubbed “Already Bad,” reportedly suggests that Justin Timberlake was not her first lover.

“I know you thought you were the first, but I had already quenched my thirst, I was already bad.”

“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.”
