Kevin Federline celebrated his 40th birthday over the weekend at a strip club in Las Vegas amid a child support battle with ex Britney Spears.

Federline Turns 40

Federline entered the big forties in true Vegas style on Saturday, March 24, at the Crazy Horse III Gentlemen's Club in Las Vegas.

The DJ and dancer, who shares two children with Spears, 12-year-old Sean Preston and 11-year-old Jayden, celebrated his 40th birthday at the popular Vegas establishment with wife, Victoria Prince, and a group of friends on Saturday night.

He arrived at the strip club in casual attire, wearing a black Cookies Clothing sweatshirt and gray sweatpants and posed for pictures with scantily clad dancers at the venue. The club also presented him with a birthday cake made to look like stacks of $100 bills printed with his face, and the icing on the cake read, "K-Fed is Fu$king 40!"

Federline then celebrated his milestone birthday by showering $200 bills on dancer with a money gun before taking over the DJ console and spinning tracks by Beyoncé, Drake, and Khia.

"I feel like the older I get, the younger I still am in my soul," he said before entering the establishment. "Another thing, the older I get the more I really appreciate my family more. You enjoy your kids and my wife and the time that I have with them. It's very precious and short."

Federline's Ongoing Child Support Battle With Spears

Over the last few weeks, Federline filed a request with his estranged wife and her father, Jamie, to increase his child support payments from $20,000 to an unknown figure, stating that it is not sufficient for him to take care of his two sons at the same level as the "Toxic" hitmaker.

Federline cited that Spears' was now making more money thanks to her Las Vegas residency. The singer raked in more than $137 million over her four-year Piece of Me show at the Planet Hollywood Resort & Casino in Vegas, which ended on New Year's Eve in 2017. However, Federline couldn't point out any specific needs that had not been fulfilled, and therefore, his request was denied by Jamie.

The estranged couple tied the knot in 2004 and welcomed their two sons before calling it quits on their marriage in 2007. K-Fed made a whopping $1.3 million from the divorce at the time plus spousal support from the singer for several years thereafter.
