Wearing what appears to be a Sensei’s pink robe, a drunk and bubbly Diane Keaton pulled red wine from her purse and told Ellen DeGeneres all about her role in The Big Wedding. “Do you know what tantric sex is … the Audience?” she asks. “Look, I’m Diane and the character I play is someone else … The definition is something like, well, when you have tantric sex you go for a long time and you have that thing called the orgasm. For nine hours! That’s ridiculous.” She then breaks down in giggles, revealing that Topher Grace plays a 29-year-old virgin (“I don’t know a man who’s 29 and a virgin … “) and that she gets up close to Robert De Niro ("I enjoyed the kissing of the men … And I put my head on his chest. And his chest did not have clothes on”). Was there an open bar at this Big Wedding, though? If so, we’ll be seeing it.
