EXCLUSIVE: So what’s the “gigantic project” Larry David and Jerry Seinfeld alluded to on Reddit last week? I can tell you because Larry told me last night while we cooled our heels at Soho House LA’s big CAA party. Soho House LA is divided into two areas, the outside “patio” and the inside dining room. If you don’t get to whatever event is going on and get right out on the patio, the LA Fire Marshall shuts it down for overcrowding. So Larry (and I) and a lot of A listers wound up on the dining room side, along with Sting and Trudie Styler, Alfre Woodard, Michael Fassbender, Brett Ratner, Ryan Coogler, Steve Coogan, and many many more. It was, as they say, LOL.

Larry, whose hilarious HBO movie “Clear History” I just re-watched, told me: “I’ve written a play.” A play? For, like, Broadway? “Yes.” And Jerry would star in it? “Maybe,” he said. “We’re talking about it.” Or directing, or producing, sounds like. Don’t forget, Jerry produced and directed Colin Quinn’s one man show on Broadway.

I miss “Curb Your Enthusiasm,” I told Larry. I can’t report that he said, “Oh yes, I’m writing the new season.” I got the impression that the play– a comedy, of course– is the number 1 project on his plate. So there it is. Just a guess: Larry and Jerry could wind up debuting their play off Broadway, at something like the Atlantic Theater Company. It’s where a lot of others– like Woody Allen and Ethan Coen– try out shows.

Meanwhile: Sting and Trudie were in town to see their new grandchild.

Alfre Woodard just accepted role in “Mississippi Grind” directed by Anna Boden and Ryan Fleck. Brett Ratner is busy finishing up “Hercules.” Bill Maher is preparing for a new season of “Real Time.” I met famed cinematographer Sean Bobbitt, who shot “12 Years a Slave” and “The Place Beyond the Pines.” So you know, it wasn’t a total loss.

Eventually we got onto the patio. Here’s what I can tell you: Jennifer Aniston and Justin Theroux are a lot of fun. I told Jennifer, facetiously, how much I love reading about her in the tabloids. “Can you believe?” she said. “It’s all made up! How do they do it?” Note to tabs: these two are happy as clams. Clams should be so happy!

Bradley Cooper was sequestered with producer pal Bryan Burk, who works with JJ Abrams. Tim Tebow was making the rounds. He is a large human being. Tony Goldwyn and I talked about “Scandal” and how everyone loves Kerry Washington. A lot of people wanted to meet Oscar Isaac. “12 Years” director Steve McQueen looked bemused by the whole thing. Marlon Wayans (I love the Wayans family–guilty pleasure) talked about his new “Haunted House” movie. Jason Binn invited everyone to his DuJour magazine party today honoring cover star Lupita Nyongo.

Favorite moment of the night: Gwyneth Paltrow and Chris Martin. I’m glad I wasn’t on the Titanic with them. Viva la vida!

They may all still be there!
