A former bodyguard is claiming Britney Spears beat one of her young sons with a belt and forced both boys to eat foods they are allergic to, resulting in them becoming violently sick. British paper The Sun reports that Fernando Flowers quit his job due to Britney’s erratic behavior. He apparently told the Los Angeles Department of Children and Family Services he feels Britney is too unstable to be left in charge of her sons — Sean Preston, 4, and three-year-old Jayden James. A source told the paper: “Britney doesn’t mean to be a bad mom. But Flores feels she has so many issues she can’t be trusted around her boys. He claims the first really shocking incident was when she came marching into the pool house at her mansion and demanded his belt. He handed it over but then followed her into the main house and claims he witnessed the alleged incident.” Flores also claims Britney constantly walked around naked and sexually harassed him.
