Kevin Federline is ready to take Britney Spears to court over child support increase, source says (Exclusive)

Britney Spears’ Las Vegas residency and worldwide tour, Britney: Piece of Me, has been a huge success for the singer, and now her ex-husband, Kevin Federline, is hoping to see some of that success reflected in larger child support payments.

A source close to Federline -- who has had full custody of the couple’s two sons, Sean Preston and Jayden James, since 2008 -- tells ET that he wants an increase in child support and is willing to take the pop star to court to get it. “Kevin wants to ask them to consider paying an amount of child support that would be appropriate given the significant increase in her finances,” the source says.

Spears kicked off her Vegas residency at the Axis at Planet Hollywood on Dec. 27, 2013, and performed her final show on Dec. 31, 2017, with a worldwide tour of the same name scheduled to continue this year. Billboard reported that the residency alone grossed $137.7 million, with nearly 1 million seats sold.

Given her recent financial success, the source says, Federline feels like he deserves more in child support payments, noting that the dancer and reality star currently receives around $20,000 a month from his ex-wife. “Kevin could have done this years ago, but he didn’t. If he had, he would have been receiving two or three times the amount of child support that he has been receiving,” the source explains.

The source adds that Federline hoped to amicably work out new child support payments with Spears, but they haven’t been able to come to an agreement, noting that the matter could go to court “soon.” “[Kevin] was disappointed that they couldn’t sit down and resolve this amicably.”

The source insists that relationship between the exes -- who married in 2004 and finalized their divorce in 2007, after welcoming Sean and Jayden in 2005 and 2006, respectively -- is “cordial,” explaining that Federline’s request for increased payments stems from a desire to provide for his sons.

“They come from a place where they will buy everything the boys will need,” the source says, referring to Spears, who has been dating model Sam Asghari since 2017. “Kevin wants to get the appropriate child support so that he too can pay for those things.”

“Kevin has gone beyond what’s reasonable to make sure [Britney] has full access to the boys,” the source adds. “He has full custody but he shares the time with her. Kevin has always allowed her to have more time with the boys.”

ET has reached out to Federline’s lawyer, Mark Vincent Kaplan, as well as reps for Spears for comment.
