Secret Witness Arrives to Testify Against Britney Spears; Train Wreck's Attorney Calls it Quits

It's hard to believe that the life of Britney Spears could get any worse, but reports suggest that her custody fight with ex-husband Kevin Federline is getting worse by the day.

First, there's the "secret witness" (pictured entering court today) that attorney Gloria Allred is produing - a person said to be the trump card K-Fed is counting on to win custody of Jayden James and Sean Preston.

Reports suggest this mystery person may be a drug dealer or bodyguard, but that remains unsubstantiated. Federline's legal team has already subpoenaed everyone from Daimon Shippen to Alli Sims and Larry Rudolph in the case.

As for Britney Spears' legal team? That's in turmoil as well.

Laura Wasser will officially submit legal papers formally withdrawing herself as the singer's attorney today, with sources saying Britney Spears' new lawyer will be another high-profile attorney by the name of Marci Levine.

Despite Spears' drinking habits, stint in rehab, repeated endangering of Sean and Jayden, and pattern of clubbing with no underwear, the cutthroat Wasser was somehow able to hammer out a 50-50 custody split with K-Fed.

But reportedly Britney was a problem client who just didn't listen and follow the advice Laura Wasser gave so Spears could maintain that custody and end this war.

Now Federline wants 70-30 custody, and it's someone else's problem, bitch.
