Kevin Federline is revealing what his future in show business could have looked like if he just said "yes." "Everything from Big Brother to Wife Swap landed on my desk," the former backup dancer, 47, alleged in his new memoir, You Thought You Knew, out on Tuesday, October 21, claiming that "reality TV offers flooded in" after he appeared on Celebrity Fit Club in 2010. "They even floated my name as a potential host for Dancing with the Stars when the show first started, but I turned it down," he continued.
