Internet Mogul Off the Hook for Good

How's this for a bad week: You plead guilty to tax evasion on Monday because you didn't pay taxes on your call girl moolah ... the next day, your hubby files for divorce.

So is the life of Cristina Schultz Warthen -- a Stanford law grad who allegedly boasted online she paid off her student loans by working as a high-priced hooker.

Warthen was indicted in 2003 -- a year before she married the founder of Ask.com, David Warthen.

So Monday Cristina agreed to pay back $313,134 in fines. Warthen's Tuesday divorce filing cites irreconcilable differences. Ya think?
