"I knew he was married and it was not something I approved of," McCready said from her home in Fort Meyers, Fla. "He was always the perfect gentleman. He had openness about him and would talk about his kids."
McCready said she thought Clemens met her daughter when she was 17. Their relationship did not become physical until 1998 when she broke up with her then fiancée Dean Caine, who played Superman on ABC's "Lois & Clark."
Mindy McCready could not be reached by ABC NEWS.com, but told the Daily News that she "could not refute anything in the story," the paper published Monday about the affair.
Rusty Hardin, Clemens' Texas-based lawyer, was unavailable for comment. In a statement released Monday to the Associated Press, he called Mindy McCready a "longtime family friend."
"Mindy McCready is a longtime family friend of Roger Clemens and the Clemens family," Hardin said in a statement Monday. "At no time did Roger engage in any kind of inappropriate or improper relationship with her. It is unfortunate that the Daily News has chosen to report anonymous allegations that are completely unfounded, have no basis in fact, and have nothing to do with Roger's baseball career or the issue of steroid use in baseball."
