Is Britney about to lose custody of her kids?

Leaked court documents expected to be released on Wednesday, suggest that Britney Spears is about to lose custody of her two sons and they will be staying with their father, Kevin Federline. She has had a lot of trouble of late, reportedly checking into rehab 3 times after shaving off her hair. Last month she tried a comeback at the MTV awards and it seems that Britney is not doing well in her professional or personal life. Can she turn matters around?
