Here's an idea... get a job!

Kevin Federline has filed papers to get his child support payments from ex Britney Spears increased, because he thinks the current amount of $20K-a-month for their two sons is not enough!

"We gave them ample time and opportunity to settle Kevin’s child support modification increase, and they came back with conditions that are not reasonable. It’s their position that they don’t have to turn over Britney’s financial information, including tax returns, which is required under the California family code. It’s not California celebrity code edition, she has to comply. This is the choice they have made, and they will now have to deal with it. We are still open to try and settling this without judicial intervention," his lawyer Mark Vincent Kaplan told Us Weekly.

The former backup dancer claims in the documents that he only earns approximately $3000 a month from DJ'ing. His plan is so clearly to live off the pop princess for the rest of his life! Not only that, but he has four other kids to pay for, which is obviously why he's begging for more dough.

"A court hearing will be set, and the parties will engage in financial discovery, which will enable guideline support payment that Kevin should receive. This won’t be difficult for us, Kevin is asking for the reasonable needs of the children to be met, which is at least three times the amount Kevin is currently getting. This is based on her earnings which have been publicly reported. We are also asking for attorney’s fees because it didn’t have to come to this," Kaplan added.

Maybe he should have thought about his financial situation before having half a dozen children with different women!
