After denying reports that she flirted with Tiger Woods, singer Jessica Simpson said she knew about Woods' cheating ways, according to Bill Zwecker a columnist for the Chicago Sun Times newspaper.

Woods' behavior was well known among many people in the sports world, the writer reported citing an anonymous source.

Simpson learned about Woods' behavior from her ex-boyfriend Dallas Cowboys' quarterback Tony Romo, Zwecker says. 

Jessica had no interest in hooking up with Tiger, for that reason alone, the paper notes.
