Star magazine reports this week that the reason Al Gore and his wife of 40 years, Tipper Gore, have recently split up was because the former Vice President was having a two-year affair with Laurie David, the ex-wife of Hollywood television producer and comedian Larry David (Seinfeld, Curb Your Enthusiasm). The two sets of couples were friends but things got closer between Gore and Laurie David after she and Larry David divorced in 2007 amid allegations that she was cheating on him with the caretaker of their Martha's Vineyard home. The money quote:

“Al and Laurie went from friends to lovers,” an insider tells Star. “It couldn't be avoided.”

Were Gore, a notorious friend of Hollywood's movers and shakers, and Laurie David getting it on in L.A? It's not clear. Of course, Star's online report is just a teaser. You'll have to pick up the magazine, which comes out Wednesday, to get the deets.
