As Britney Spears prepared to check herself out of rehab last night, it seems she was also tying up some loose strings elsewhere in her life.

Evidently Spears met with estranged husband Kevin Federline over the weekend to put the final touches on their divorce.

For now, it looks like Britney and K-Fed plan to split custody of the kids (50/50).  Eventually Spears will have primary custody and Federline will have standard visitation rights.

No word on how much Britney will help Kevin financially.  

Word is that she decided to leave the Promises rehab center a bit early so she can attend Kevin's birthday bash that has now been cancelled.
