Yep, Bert and Ernie are more than just friends according to Mark Saltzman who joined 'Sesame Street' as a writer in 1984. He revealed the news with "The Queerty" during a recent interview. Another Sesame Street writer named Gary Knell denied the same rumors in 1994 during an interview with "The Independent". In 2011 'Sesame Street' released a statement saying that Bert and Ernie were "just friends" and "do not have a sexual orientation" which is very similar (almost identical) to the statement they released today.
