The rapper believes that Britney's bizarre behaviour - which included pantyless partying, shaving her head, going to rehab, serving her mother with an order to stay away from her sons - would never have happened if she had not met Federline.
"I think she brought too many people in. Kevin whatever his name is, who is he? She made him a star. She should have left his ass in the closet, then he would have stayed and everything would have been exactly the way it needed to be," Contactmusic quoted him, as saying.
In the meantime the singer's woes continue to intensify as she is now being investigated for possible child abuse.
The news comes when Spears is involved in a legal battle with ex-hubby Kevin Federline over the custody of their two kids.
The Los Angeles County Department of Children and Family Services (DCFS) has accused the pop star of being an unsuitable mother after reports of her erratic behaviour were filed.
According to reports, Los Angeles Superior Court took up an unscheduled court hearing on August 2.
The mum of two has been repeatedly charged of being irresponsible.
Recently she is said to have spent the whole night with magician Criss Angel drinking Dom Perignon champagne.
The next hearing for the custody case has been scheduled for September 4.
