London, Oct 11 Sales of squirrel meat are soaring in the US, all thanks to Britney Spears.

A biography of the pop princess, published in the US, has revealed that the singer's family was so poor in the past that they ate anything her dad Jamie could hunt.

And thus, fans who want to get a taste of the 'toxic' singer's trailer park childhood are snapping up squirrel, rabbit and possum from butchers and restaurants.

The biography, titled 'Britney: Inside The Dream', by British author Steve Dennis, has been launched recently.

Meanwhile, the pop star is making new efforts to gain full custody of sons Sean Preston, four, and Jayden James, three.

Pals have claimed that Britney, 27, aims to petition Los Angeles Superior Court to get them back from ex-husband Kevin Federline, 31.

"She wants the roles reversed," The Daily Star quoted a pal as saying. (ANI)
