According to The Blast, the former back-up dancer allegedly had his lawyers send Britney’s team a letter asking that they renegotiate the amount he currently receives for the couple’s sons, Jayden and Sean.
Presently, the father-of-six receives $20K a month from Spears, although she has primary custody of the two boys.
Apparently the amount of child support was based on how much the pop diva makes and because her Vegas residency has been very lucartive, Federline is looking to get a bigger piece of the Spears pie.
Federline and Spears were married from 2004 to 2007.
On top of the two sons he has with Spears, Federline has two children with current wife Victoria Prince and two children with ex-girlfriend Shar Jackson.
