I guess it’s official, more or less.

Director Barry Sonnenfeld tells me that “Men in Black 3-D” is ready to roll. Will Smith has signed on, Tommy Lee Jones is in, and a script is awaited.

Yes. I did say 3D. “Men in Black 3” will be in 3D. Sonnenfeld says it is so. Why not? Everything else is, and this is one movie that might be cool in the process.

Sonnenfeld told me he’d get me a neuralizer–that’s the cigar holder like gizmo that erases memories–but he couldn’t promise it would work! (I love that thing.)

Nevertheless, you can bet Sony is juiced to get this puppy moving since “Spider Man 4” fell apart. They are in desperate need of a blockbuster for next Memorial Day May 2011. And “Men in Black” is like money in the bank.

I ran into Sonnenfeld, by the way, at Vanity Fair’s annual outdoor cocktail soiree at the New York State Supreme Court building. This is the party that launches the Tribeca Film Festival. Graydon Carter greeted each guest as they climbed the massive stairs to th e portico. Right behind him were Robert DeNiro and Grace Hightower, Jane Rosenthal and Craig Hatkoff, and everyone who’s anyone in town.

That list included Jerry and Jessica Seinfeld, Chazz and Gia Palminteri, Brian Williams, Patricia Clarkson. Google chief Eric Schmidt, Charlie Rose and Amanda Burden, Rob and Marisol Thomas, John McEnroe, Harvey Keitel, Ronald Perelman, Diane von Furstenberg and Barry Diller, Griffin Dunne, Ed Burns and Christy Turlington, Queen Noor of Jordan, Andre Balazs, Andrew McCarthy, John Leguizamo, Veronica Webb, Police Commissioner Ray Kelly, Mayor Mike Bloomberg, city councilwoman Christine Quinn, Drew and Ann Nieporent, and Oscar winning “Precious” screenwriter Geoffrey Fletcher.

Yes. just another night, Vanity Fair style! Later we ran into Uma Thurman having dinner at Carter’s Waverly Inn, while Graydon himself was said to have taken a gang up to (his) Monkey Bar.

And PS: here’s a little gossip from John McEnroe, Wife Patty Smythe, a great rocker before she settled down with John to raise six children, is in Nashville recording her first album in 20 years! Remember “The Warrior?” http://tinyurl.com/y49cdae
