Screenwriter and playwright David Bar Katz has threatened to sue editors at a U.S. tabloid for publishing fake quotes suggesting he was romantically involved with his late friend Philip Seymour Hoffman. Katz, the man who discovered The Master star's body in his New York home on Sunday (02Feb14), had reportedly sold his story to the National Enquirer, alleging the longtime pals had been involved in a secret affair. He was quoted as saying, "We were homosexual lovers. We had a relationship." Hoffman's representative has since slammed the article, telling GossipCop.com, "The story is completely 100 per cent false", while Katz has also spoken out to shut down the claims, insisting, "I never said that." A source close to Katz tells the New York Daily News, "This is a categorical, 100 per cent vulgar and disgusting lie. Even the National Enquirer should be ashamed. It's just disgusting. There will be legal action. "He never spoke to them. This is so far off from reality. We're calling lawyers now to threaten them appropriately." Hoffman was found dead from a suspected drug overdose at the age of 46. The tragic actor was reportedly living alone after moving out of the home he shared with his longtime girlfriend Mimi O'Donnell and their three young children last year (13) after suffering a drug relapse after more than two decades of sobriety.
