However, the 28-year-old star has strongly denied the claims and insisted that she has never mistreated her four-year-old Sean Preston and Jayden James, three. Meanwhile, the singer"s former bodyguard Fernando Flores, who approached the investigators, even revealed to Los Angeles Department of Children and Family Services that he feels Britney is too unstable to be left in charge of her sons.
Apparently, Flores fears her behaviour could scar for life the youngsters - who split their time between Toxic singer Britney's Beverly Hills mansion and dad Kevin Federline"s home. "Britney doesn't mean to be a bad mum. But Flores feels she has so many issues she can't be trusted around her boys, " the Sun quoted a source as saying.
"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, " the source added.
Flores also accused Britney of feeding the boys food they were allergic to, including shellfish. The alleged incidents took place in late March or early April. Child protection agency workers tried to quiz Britney last week but she had left LA for a few days.
