The New York Daily News is reporting that baseball pitching great Roger Clemens had a 10-year affair with country singer Mindy McCready that began when she was 15-years-old and lasted for more than a decade.

Roger Clemens carried on a decade-long affair with country star Mindy McCready, a romance that began when McCready was a 15-year-old aspiring singer performing in a karaoke bar and Clemens was a 28-year-old Red Sox ace and married father of two, several sources have told the Daily News.

The revelations could torpedo claims of an unsullied character that are central to the defamation suit Clemens filed Jan. 6 against his former personal trainer Brian McNamee. Vivid details of the affair could surface in several media projects that McCready is involved with – including a documentary that begins filming today in Nashville, a new album and a reality show.

Roger’s lawyer Rusty Hardin has confirmed their was a long-term relationship between Roger and Mindy but says it was not sexual in nature.

Contacted by the Daily News Sunday through his lawyer Rusty Hardin, Clemens confirmed a long-term relationship but denied that it was of a sexual nature.

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

Roger and his lawyer are not always the two most believable sources when it comes to veracity from Clemens’ past. If this is true and Clemens did start something romantic with McCready, when she was 15, then it could be ‘Jerry Lee Lewis’ devastating for the ‘Rocket’.

McCready has been in and out of jail for numerous reasons over the past couple of years. Her actions could be interpreted as someone lashing out from sexual abuse as a child or minor. She was sentenced to a year in jail and two years of probation last fall.

If ture this could be a coup for Brian McNamee in his defamation defense against Roger.

This year has been very tough for Roger’s wife Debbie Clemens. She was brought into the middle of his steroid controversy. She admitted to getting HGH shots from McNamee and now she is having to hear about an alleged affair between her husband and a country singer.
