Apparently there's someone in Britney's camp who actually has a brain cell — not whoever's in charge of making sure she has clothes on, obvs, but that'd be asking for a miracle:
Britney Spears didn't pick Nov. 6 as the day to file for divorce from Kevin Federline by accident. She filed two years and one month from the day of her marriage, on Oct. 6, 2004. Her prenup, according to legal theorists, evidently carried increases for Federline for every year of their marriage. And those deadlines, they say, likely had 30-day grace periods. Hence, Nov. 6 would have been Britney's last chance to get out of paying a third year of alimony settlement . . .
