The husband of country singer Sara Evans says she filed for divorce the day after he discovered she was having an affair.
Craig Schelske did not identify the other man in court documents filed Friday in Williamson County Chancery Court.
Evans' publicist Lori Genes declined to comment.
In his answer to Evans' petition for divorce filed last week, Schelske denies Evans' allegations that he committed adultery, was verbally and emotionally abusive, drank excessively and frequently watched pornography in their home.
Schelske, who ran for Congress as a Republican from Oregon's 5th District in 2002, says he and Evans, 35, were watching pornography together when their oldest child, a 7-year-old daughter whom they believed to be asleep, entered their room unexpectedly.
He also denies her claims that he posed for nude photographs of himself — except a few taken by his wife on their 10th wedding anniversary — as well as the existence of any sexual photographs of himself with other women, or that he had an affair with their former nanny. The nanny also has denied the allegation.
"No other photographs exist and any allegations of such are outrageous, defamatory, malicious and legally actionable," the suit states.
Schelske, 43, also says his wife's interest in her "marital roles and responsibilities" declined and she "neglected" their three children after she began appearing on ABC's "Dancing with the Stars."
