"Britney believes Kevin's been smoking pot in front of the kids. She says she can smell it in the boys' hair and on their clothes when she has her visitation with them," Conatctmusic quoted a source, as telling American magazine Life + Style. The publication has also claimed that the pop star is determined to get the kids tested to confirm her suspicions.
"She's asked the court-appointed monitor and her lawyers if they can prove the kids have been exposed to environments in which drugs have been taken," the source added. However, Federline's friend, who has rapped about his love of marijuana, insists that he 'never smokes (pot) around the kids'.
