Yes, it's true. Kid Rock will now have genetic influence on yet another generation. Kid Rock is reportedly going to be a grandfather. According to Us Weekly, Kid's son, Bobby Ritchie Jr., is currently expecting first child with his girlfriend. A source tells the site that the baby is a girl and Bobby's girlfriend has already been pregnant for four months. Bobby is Kid's child from his relationship with his ex-girlfriend, Kelley South Russell. The "Only God Knows Why" crooner won Bobby's custody in 2000, charging Kelley $25 per week in child support.
