Britney Spears was straight-faced leaving an all-day meeting with Kevin Federline and both their lawyers in LA yesterday to try and hammer out a new custody arrangement outside of court. After this week's hearing, Britney is allowed one overnight a week with Sean Preston and Jayden James while Kevin maintains temporary physical custody, but the August trial will make a more permanent decision. According to his lawyer, Kevin wants to keep sole physical custody with "substantial and meaningful" visitation involvement for Britney. No agreement was settled on yet, meaning a trial is coming our way, but apparently the talks stayed civil. Hopefully both sides can keep it that way because the last thing Britney, Kevin or the boys need is more public drama over the custody of their sons after finally reaching a bit of stability.
