Pregnant pop princess Britney Spears is an emotional wreck because she’s faced with spending the first few months of her baby’s life without her husband.

Sources say the 23-year-old superstar has been arguing with Kevin Federline over his desire to launch a music career that would leave her alone to raise their baby.

Family and friends fear that Kevin, who left his pregnant girlfriend Shar Jackson to be with Britney, may be about to repeat his old pattern of being an absent dad.

Kevin has been busy working on his first CD, spending thousands of dollars of Britney’s money, and hoping to complete the project for a December release, a close source told The National Enquirer.

Britney, who had a No. 1 hit with Toxic, is said to have had a big blowup with Kevin over his plans.

The source said: “Britney said, “I need you by my side, by our baby’s side and not on the road hundreds of miles away. I want you around for our baby’s first Christmas’.

“Kevin reminded Britney that if she’s taking time off to be a stay-at-home mom, somebody has to be out there making money. Then, he pleaded, ‘Britney! You of all people should understand!’

“She turned to her mom for consolation but I bet all she got was a dose of reality and an ‘I told you so’.”

On Aug. 17, Britney had a spat with her mom Lynne Spears. “Lynne probably reminded Britney that she brought it all on herself by getting pregnant right away,” the source said, adding that the fighting with both her mom and Kevin has put the singer closer to an “emotional breaking point.”

It was Britney, who sources say has scheduled a C-section for the middle of September, who pushed Kevin into a music career — but now realizes she wants him home. One thing they agree on — the baby’s name: Preston. “Britney wanted Jami and Kevin liked Vegas after his favorite city. But they settled on Preston,” the source added.
