Roger Clemens is misremembering again. This time it’s about who he’s had sex with that’s not named Mrs. Clemens.

Saying “all is fair game,” lawyers for Roger Clemens’ former personal trainer Brian McNamee say they intend to capitalize on allegations of an extra-marital affair involving Clemens and a country music singer in defending a defamation suit Clemens filed against McNamee.

The New York Daily News, citing “several” unnamed sources, reported on its Web site Sunday night that Clemens and country singer Mindy McCready had a decade-long affair. Clemens’ lawyer, Rusty Hardin, said Clemens and McCready had a friendship and nothing more.

“If true, it’s just another example of Roger’s pervasive prevarications which will be at the core of any defamation case,” said McNamee’s attorney, Richard Emery, in an e-mail to The Associated Press.

“He flatly denies having had any kind of an inappropriate relationship with her,” Hardin said, according to the Daily News. “He’s considered her a close family friend … He has never had a sexual relationship with her.”

The list of lies is starting to grow for Roger; and this mistress, this country singer, she better hope Mrs. Clemens doesn’t get wind of this — the woman’s hyped up on HGH, and’s probably willing to beat the hell out of some skinny country girl.
