Britney Spears and Kevin Federline Heading to Custody Trial

Custody of Britney Spears and Kevin Federline's two young sons will be settled in a trial in August, after an attempt to settle out of court failed on Thursday.

The pair spent the day in talks with a mediator, but Federline's attorney Mark Vincent Kaplan has confirmed that no agreement could be reached.

He tells E! News, "The mediation didn't result in an agreement that would avoid the trial set in August."

But he insists there was no breakdown in communication between the former couple, adding, "The mood was comfortable, positive and it was a mood that was consistent with opening at least a great dialogue, which is necessary.

"If the existing arrangement was acceptable to both parties... we wouldn't have to go to trial. But that didn't happen."

The trial is due to begin on Aug. 25, and will result in a final custody ruling.

Kaplan added that Federline is seeking sole physical and legal custody of Sean Preston and Jayden James. Federline was handed full custody of the boys after Spears was committed to a psychiatric facility to treat an alleged bipolar disorder following a standoff with police and childcare officials in January.

Spears locked herself and her youngest son in the bedroom of her Hollywood home and initially refused to come out when a visitation period had ended.

Earlier this week, Spears was granted an extension to her custody rights when a judge agreed she could spend one night a week with her sons.

Jamie Spears Thrilled with New Baby

Britney Spears and her family are "thrilled" with the arrival of Jamie Lynn's newborn daughter, reports proud grandfather Jamie.

The 17-year-old sister of pop star Britney gave birth to Maddie Briann, her first child with fiancé Casey Aldridge, at Mississippi Southwest Regional Medical Center in McComb, Mississippi, on Thursday.

And family patriarch Jamie, who was said to be present at the birth, insists the entire family is delighted with the newest member of their clan.

He tells Life & Style magazine, "We're thrilled, we're all absolutely thrilled."

Spears and Aldrige became engaged in March. The teen star stunned the Spears family when she announced her pregnancy news last year, at the age of 16. They had reportedly been delaying their wedding until after the birth of their child.

Britney Spears Avoids Charges in Car Accident

LOS ANGELES - Officials said on Monday they will not file charges against pop star Britney Spears over a photographer's claim she ran over his foot as she backed up her car in a crush of paparazzi.

A photographer filed a police report about six months after the incident in November. But prosecutors said the only way the paparazzo's foot could have been where the video showed it to be was if he himself had put it there.

Joseph Shidler, deputy district attorney, noted in a report that Spears' car was surrounded by photographers, and that a voice on the video told her to back up.

"We have no evidence to prove beyond a reasonable doubt that the suspect was aware that the victim's foot had been struck by the car," Shidler wrote. "There was much commotion and noise at the time and there is no proof that the suspect was aware of what had happened."

Prosecutors said the video, which circulated on the Internet, does not show the photographer's foot being run over. But Shidler added that, "the only way the victim's foot could have been where the video indicates it to be was by the victim placing it in that location."
