Mel Gibson: Baby Mama Gunning for Epic Payday

EXCLUSIVE

Mel Gibson clearly loves his little daughter, but he's gotta be regretting hooking up with the kid's mom, who's going back to court for a bloody fortune.

Sources familiar with the case tell TMZ, Oksana Grigorieva is asking the family law judge to increase her child support from $20k a month to well over $100,000 a month.

Our sources say Oksana wants significantly more than $10k a month just for security, even though we're told she can't point to any security risk involving 6-year-old Lucia.

The case is about to go to trial, with Oksana claiming she needs to support a lifestyle of vacations, travel, lodging and other items that make Mel look like mobile home material.

TMZ broke the story, Oksana got $20k a month and a house from Mel after a brutal legal fight.
