Sam Asghari Takes a Shot at Britney Spears’ Other Ex-Husband Kevin Federline Following Memoir News

Britney Spears isn’t the only one up in arms over ex-husband Kevin Federline’s upcoming tell-all — now another of her exes, Sam Asghari, is getting into the ax-grinding act.

“It would be the first book that’ll tell you how to be a professional father,” Sam, 31, said in an interview with TMZ — implying that Kevin can boast about his parenting skills only because he was paid so handsomely from the divorce settlement to sit around.

Britney, 43, and Kevin, 47, share sons Sean, 19, and Jayden, 18, but the former backup dancer has had majority custody of the boys since October 2007.

Now that both kids have reached legal age, the $20,000 monthly support payments have stopped — but that’s after she paid Federline a reported $5 Million over the 17 years since their divorce, including an initial $240,000 per year that was later increased to $480,000, plus tuition and other fees.

Fans of the “Toxic” singer have also slammed Kevin for the “cash grab” of writing the memoir You Thought You Knew precisely after the child support payments dried up. The book is due out in October, per Daily Mail.

“His timing tells you everything,” posted one skeptic on Reddit.

A press release for the book promises to reveal “extremely intimate and transparent” details about the “highly publicized marriage,” which lasted from 2004-2007.

Brit went on to marry Sam in June 2022. They split in August 2023, with the divorce finalizing in May 2024.

“I achieved my biggest dreams, dealt with crushing heartbreak and endured constant ridicule, all while becoming the father my children needed as they experienced non-stop emotional turbulence,” boasts Kevin in the book’s press release, per TMZ.

It goes on to say: “The public unraveling of Britney’s life and the constant attention around their family forced Kevin to balance being a father with being a protector.”

Kevin — who boo-hoos that he’s “one of pop culture’s most misunderstood figures” — also has daughter Kori and son Kaleb with his ex Shar Jackson, and shares daughters Jordan and Peyton with current wife Victoria Prince.

The preening pop’s memoir arrives almost exactly two years after Britney’s book The Woman in Me.
