Has Britney Missed Another Deposition?

Britney may have blown off yet another deposition in her ongoing custody battle with Kevin Federline, her second in two days, according to Ok! Magazine.

Apparently, Brit was scheduled to be deposed this morning at 9:45, but didn't leave her house until after 10.

However, once en route, with pal Sam at her side, Brit got cold feet and turned the car around.

Sam still claims that Brit will show at the depo, but she may have already missed her last chance; according to the mag, Kaplan may already be headed to the courthouse "to ask the judge to dismiss Britney's custody claim and give Kevin permanent custody."

UPDATE: Sam is now telling reporters that Britney is, indeed, a no-show! Is this the end of her custody battle?
