A tape of an "Entertainment Tonight" interview with actress Anne Heche is missing, and the show's lawyers want to know where it is. New York's Daily News reports that Heche did the interview to promote her new movie, "Psycho," and was asked to respond to rumors that she may have been romantically involved with co-star Vince Vaughn while making the film. A source tells the Daily News that Heche, who lives an openly gay life with Ellen DeGeneres, was insulted by the question, cut short the interview and left with the tape. But a Heche spokeswoman says the actress "finished the interview and never left with the tape and doesn't have it now." ET's lawyers are asking the actress what exactly happened.
