Kevin Federline's pre-nuptial agreement reportedly states he will get more money for every child he has with wife Britney Spears.

The former dancer - who is setting up his own record label after industry bosses snubbed his PopoZao single - is expecting his second child with the Toxic singer in October and it seems he has more than one reason to celebrate the birth.

A source revealed to the MSNBC website: "Before he got married, Kevin was sitting down with lawyers, discussing legal and financial issues.

"He was sitting sort of slumped over with a baseball cap over his eyes and a lawyer was talking about how he had to sign a pre-nup and Kevin looked sort of bummed out.

"But then the lawyer explained that for every child the two of you have together, you would receive X amount of dollars. His eyes really lit up."
