Mindy McCready, Baseball Mistress, coming April 19, will feature the Celebrity Rehab star as the country singer "takes it off and gets it on with a boyfriend named 'Peter' in the tape that contains almost an hour of action," says a news release from Vivid Entertainment (the same company that released Kim Kardashian's sex tape).
On the video, McCready discusses ex-lovers, including ex-fiancé Dean Cain, and her alleged relationship with country singer Alan Jackson. She says she "took a shower and had oral sex with Clemens when she was only 16 and he was 29," and adds that Clemens was "good" in bed "when he could get it up."
McCready told the New York Daily News in April 2008 that she had a long-term affair with Clemens.
Clemens, nicknamed "The Rocket," is under investigation for perjury after he testified before Congress in 2008 that he never used performance-enhancing drugs, according to the Daily News.
A rep for Roger Clemens did not return a call for comment.
Vivid is also including a bonus sex video, Tom Sizemore Sex Scandal, featuring McCready's Celebrity Rehab co-star, which was first released by Vivid in 2005.
According to a Fox News report, McCready, 34, also took a swipe at Oprah Winfrey, calling her a racist and saying she allegedly told her she should have been strong enough to escape an abusive relationship because she is white.
A call to Winfrey's rep was also not immediately returned.
McCready was hospitalized in 2005 after being assaulted by ex-boyfriend Billy McKnight, who was charged with attempted homicide. She has had run-ins with the law on drug charges as well as probation violations — and survived at least three suicide attempts.
The singer first arrived on the music scene at age 18 when her Ten Thousand Angels debut album sold 2 million copies. McCready's new album I'm Still Here was released March 23.
