According to US reports, Britney has hired a private eye to record her mother's phone calls. It's said that the investigator was able to uncover proof that her mother was still in close contact with the Britney's ex-husband Kevin Federline.
Britney then showed up personally with a CD of the phone recordings to confront her mom. She also accuses her of abusing prescription drugs, and falling asleep when she looks after the star's sons Sean Preston, 21 months, and Jayden James, nine months.
I really don't think Britney mental capacity to hire her own private investigator. She probably just met some guy at a bar with a mustache who flashed his Female Body Inspector card and was like "y'all is hired to sneak on my momma, she ain't doing me no good no more...now time to lick gravy off ma fingers!! yum!!"
