Star magazine reports Eminem was devastated when ex-wife Kim Mathers was sentenced to 30 days behind bars for violating her probation by testing positive for cocaine use. “Oh man, my Pooh Bear,” a source said the rapper cried to a family member. “30 days in the can!” Slim’s uncle Todd Nelson said, “She’s having a tough time of it in jail. She’s in the general prison population, but if there are any problems she could be placed in protective custody. After all, she was the wife of a big celebrity and still has strong ties to him.” Nelson added that after the legal issues with Kim are resolved, Eminem is seriously considering moving out of Michigan for good.
