Pop princess Britney Spears and her husband, Kevin Federline, are choosing names for their baby, who is expected this September. It is seems that Britney and Kevin cannot agree over how to call their unborn baby if it is a boy.

Britney likes the name Charlie, especially after she saw "Charlie and the Chocolate Factory", but Federline does not approve her, arguing he wants the baby to be called just like him, Kevin Jr.

A friend is quoted by Britain's Daily Star newspaper as saying: "Kevin loves the idea of naming the child after him. But Britney has dug her heels in and loves Charlie. She feels Charlie is a great name for both sexes and her little sister Jamie Lynn agrees."

Meanwhile, beautiful singer and actress Jessica Simpson advised Britney and her husband, Kevin Federline to renounce to their reality show "Britney&Kevin: Chaotic" after the first series, before it ruins their lives.

Simpson confessed they were tight up by the contract to do three series of their reality show, "Newlyweds: Nick and Jessica" and she regrets she lost two years of their lives.
