Perhaps there is indeed more to the Al and Tipper Gore divorce that seemingly came out of nowhere and ended a 40-year relationship.
According to Star Magazine, Al Gore had been having a two-year affair with Laurie David (pictured left), an environmentalist who was once married to comedian/actor Larry David.
Laurie David has already issued a statement denying the story: "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.The story is completely untrue."
Meanwhile, the New York Daily News says a close friend of the Gores -- who is also nameless -- "laughed at the report" and said it was false.
But Star Magazine quotes an unnamed source who says, "Al and Laurie went from friends to lovers. It couldn't be avoided."
Laurie David is a trustee for Natural Resources Defense Council. She also co-produced Al Gore's Oscar-winning documentary An Inconvenient Truth.
