Kevin Federline?s lawyer believes that he deserves ?at least three times the amount? of child support that Britney Spears currently pays him. ?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,? Federline?s celebrity divorce attorney Mark Vincent Kaplan exclusively told Us Weekly on Tuesday, May 22. According to court documents obtained by The Blast, Federline, 40, filed documents to request more child support from the 36-year-old pop icon on Tuesday.
