Britney Spears' ex-husband, Kevin Federline, is not happy with the current arrangement between the two. After receiving a total of $20,000 dollars for child support, Federline is alleging that isn't enough to take care of the former couple's two boys.

Federline now is seeking more money from his former spouse and bringing her family into the drama.

K. Fed Is At It Again

The former backup dancer and his attorney reportedly contacted Spears' father, Jamie and requested more money for child support. Federline is claiming that he can't take care of his two sons, Preston and Jayden, that he shares with the singer on her level. The amount that Federline is asking for is currently unknown.

Federline is claiming that Spears new residency at Las Vegas is only possible because he is able to have their sons which won't interfere with Spears performing and being gone often. Spears' father has reportedly denied Federline any more money.

"The lawyer repeatedly talked about Britney's recent successes - particularly her sold-out Las Vegas shows, saying she's making a lot more money. Jamie kept pushing back saying Britney's success has nothing to do with the needs of the children, and his daughter wasn't responsible for taking care of Federline and his other family members," a source close to Spears claimed

In addition to his two sons he has with Spears, Federline also has two children, Kori and Kaleb, with his former fiancee Shar Jackson, and two more daughters, Jordan and Peyton, with his current wife, Victoria Prince. Federline and Spears were married from 2004 to 2007. Prior to her relationship with Federline, Spears dated former N'SYNC member, Justin Timberlake, from 1999-2002 and impulsively married her childhood friend, Jason Allen Alexander.

The marriage was annulled after 55 hours. 

The pop singer began her Las Vegas residency in September 2013 after confirming the news on Good Morning America. Currently, the "Hit Me Baby One More Time" singer is earning $15 million dollars per year.

In January 2018, Spears announced that she would be taking her residency show on a summer tour. The tour is expected to begin in July 2018 in North America and Europe.
