Apparently, Kevin Federline forced Britney into rehab by threatening to battle her in court over the custody of their two children if she did not check herself into rehab.
Spears was then believed to have suffered from post-partum depression and became emotionally unstable from going through divorce. She was further put under pressure by the media constantly following her every move.
Spears and her assistant, Allie Sims, called Promises rehab center and requested her drug and alcohol test. Her rep was sent two reports which showed no alcohol or drug use at all. The first report was dated 15 days after Spears checked in. There is no report that Spears ever tested positive for drug or alcohol use.
The pop princess fired her manager and won?t speak to her mom as a result of her time in rehab.
