In a story published Oct. 18, the paper alleged that instructor Edit Pakay had a "full-blown sexual affair" with the "Californication" star, who recently announced his separation from wife Tea Leoni.

In documents filed in Los Angeles Superior Court and obtained by Access, Duchovny has sued the Daily Mail for defamation and false light invasion of privacy, and calls for a jury trial.

An attorney for actor David Duchovny has released a statement denouncing reports the "Californication" star was involved in an affair with a tennis instructor.

Following a report in Britain's The Daily Mail, which claimed Duchovny had an affair with a woman named Edit Pakay, attorney Stanton "Larry" Stein issued a statement refuting the alleged romantic relationship, claiming that "the article contains false and defamatory information."

However, Duchovny is denying having an affair with Pakay.

"In light of continuous speculation over the lives and marriage of Tea Leoni and David Duchovny, the couple has confirmed that they have in fact been separated for several months," reps for the actors told the mag in a statement. "The couple had hoped to keep this separation private for the sake of their children."
