A source close to David, who split from Seinfeld creator and Curb Your Enthusiasm star Larry David in 2007, adds, "As far as I know, they haven't even spoken in two years. I have no idea where this came from."

David, 52, told the Huffington Post, "It's a total fabrication. I adore both Al and Tipper. I look at them both as family. And I have happily been in a serious relationship since my divorce."

Gore, 62, announced his split from his wife of 40 years, Tipper, on June 1, calling it, "a mutual and mutually supportive decision that we have made together following a process of long and careful consideration"
