Roseanne Barr is coming to Broadway. Maybe.

“That is, I could be coming to Broadway,” she said. “I sure want to. And nobody knows this. I haven’t told anyone. You’re the first to know. That is, if there’s something to know . . . actually, it could even be off-Broadway. Right now it was just a reading, but I’m excited at the possibility. Look . . . who knows?”

A slimmed, calmed, gray-haired Roseanne, wearing tinted glasses, said: “I don’t exactly know how this all came about for me, but Ethan Hawke, who has his own company, The New Group, is behind it. A play called ‘Blood From a Stone’ was written by a first-time playwright, who, if you can believe it, actually works as a security guard. It’s probably the best part I ever had in my whole life. I play a crazy mom who does things like folding laundry, and it’s a dysfunctional family, which is certainly something I have firsthand knowledge about, right? Ethan said he thinks this play, which is a combination of drama and comedy, could actually win a Pulitzer.

“Anyway, we did a reading here Monday, which is what I came in for, and it’s with director Scott Elliott and great actors like Philip Seymour Hoffman and Natasha Lyonne, and I’m not exactly sure how it’ll work because I never did anything like a reading before. Especially with the playwright himself sitting right there.”

Told it’s just like the table read she and her TV cast did every week with each new episode’s script, Roseanne, who is now already back in LA, said: “Yeah. I know. But still I was nervous. And excited. Oh, wouldn’t I just love to be on Broadway. Anyway, they said they definitely want me and I know I definitely want it so . . . we’ll see . . . ”

We first talked at intermission of David Mamet‘s new play “Race,” which, by the way, is a terrific high-speed ride. “Race” makes your blood race. Being less knowledgeable than my more cultured drama critic brethren, I only know I loved it. Everyone I know loved it.

Mamet wrote “Race” last spring and so loved this Broadway directing debut that, rather than miss one day’s work, he canceled returning to LA and family Thanksgiving. His comment now? “I’m sad the creative process is over.”

Roseanne attended “Race” with Laurie Metcalf, who did nine years on her TV show, and she said, “I’ve never, ever been to a New York theater opening before. This is my very first. Laurie’s taken me.”

Although not about to spout: “Out, out, brief candle!” Roseanne Barr is definitely into the legit thittir.

Woody Allen, by the way, also showed on this opening night in a pullover sweater. Didn’t even look new . . . Edie Falco on her “Nurse Jackie” TV show: “We’re now ending Season 2. My fingers are crossed we continue. We go on hiatus to re-air in March, and that’s when we’ll know if we’re picked up. Until then I’m praying — but meanwhile I’m looking around.” . . . And Alec Baldwin on his stated political ambitions? “Not right now. There’s no available slot in New York. Everything’s basically locked up. When a pathway frees up, I’ll think about it again.” . . . Note to Tiger: Research finds good people live longer than bad people — unless the bad one aggravates the good one.

Tomorrow ABC announces officially George Stephanopoulos takes over “GMA.” Also that he’ll be permanent sit-in replacement for nightly news anchor Diane . . . Per Washington’s primary hostess Buffy Cafritz, DC is quiet this holiday. VIPs are just coming off the Kennedy Honors. About un-VIPs, I didn’t ask. I don’t care . . . So is maybe George Pataki maybe running for senator, maybe? Libby Pataki told me: “I’d be supportive, except I don’t think he or I basically want it. But what he wants is for things to change, so he’d only make the run if he thought he could help.” . . . Major media investigation’s under way into TV’s political talking heads who have conflicts of interest with the White House and Congress. Just telling you what I know.

AT political power couple Liz Robbins and Doug Johnson‘s annual holiday party: Chelsea Clinton accepted congratulations and talked about her happiness in getting married. Lt. Gov. Richard Ravitch talked about Obama‘s health-care bill costing New York $1 billion when it starts 2013. Joy Behar talked about Joy Behar. On her 9 p.m. nightly HLN-TV show, she just interviewed Levi Johnston, whose fame comes from his Johnston. This nobody kid now has a bodyguard. Whose name is Tank. What is it with that Alaska group’s names? Trig, Track, Tank. Anyway, this nice, dear, charming young man, who speaks monosyllabically because he can’t put a sentence together, is meeting with book publishers to do more on doing in Sarah Palin. He also chewed tobacco in the Green Room.

STILLER & Meara’s Anne Meara to a female on TV: “You’re my idolette.”

Only in New York, kids, only in New York.
