Kevin Federline is naming names. In his new memoir, You Thought You Knew, the former backup dancer calls out Rosie O'Donnell, Jimmy Kimmel and other celebrities who publicly mocked him during his divorce from Britney Spears. "The gossip, the rumors and the public ridicule, it's all like a high school drama on a massive scale. And while I was lucky to have a strong sense of self by the time fame hit, there were still moments that got to me," he writes in the book, which was released on Tuesday, October 21. Federline, 47, acknowledges that he "expected" Spears' "most loyal supporters" to "lash out" at him, but he was taken aback when other stars followed suit. Britney Spears and Kevin Federline's Timeline: From Divorce to Coparenting "What stung was when people in the industry, the so-called Hollywood elites, jumped on the bandwagon without knowing me at all," he continues. "When someone like Ben Stiller or Rosie O'Donnell makes a jab, it feels personal. It'd be one thing if they were strangers, but these were people in the same world, people who should understand how damaging words can be.

"That moment summed up how the industry treated me, like I was something to be laughed at, thrown away and forgotten," Federline writes in his memoir of Kimmel's bit. "That hurt. It's one thing to deal with the tabloids, but it's another when the ridicule comes from people you once respected or people who should know better."
