Penny Marshall didn’t know some of the people at her book party Wednesday night at New York’s Monkey Bar. Of course, there were the friends — Barry Diller, David Geffen and Lorne Michaels put the party together in honor of Marshall’s new book, “My Mother Was Nuts: A Memoir.” Ron Perelman has known her for 30 years.

“We met when she did a commercial for us at Revlon and we became best friends,” Perelman said. “She’s like one of my sisters.” He didn’t know, though, if he was in the book. “I haven’t read it,” he said. He is, in the acknowledgments.

There were the actor friends. Carol Kane, who once played a gypsy, Olga, in “Laverne & Shirley,” and frequent movie heavy Robert Loggia, Tom Hanks’ boss in “Big.” But there was also Wendi Deng.

“Who?” Marshall blared in her trademark honk, speaking a day after the party. She perked up when the other last name came up — Murdoch.

“I don’t know who she is. I know Rupert,” Marshall emphasized. “He owned a studio I worked for.” That would be 20th Century Fox, which released “Big.”

Marshall does know Mariah Carey, who got to the shindig late — as Perelman, Fran Lebowitz, Graydon Carter and John McEnroe were already around one of the long booths in the mezzanine ordering dinner. “She came from the studio,” Marshall explained of Carey’s tardiness.

“I’ve known her for 18, 19 years,” Marshall said. “We hadn’t seen each other since the baby shower.”

Marshall’s been doing nonstop press for the book. “Talk fast,” she said on the phone Thursday. And as part of the rollout, she got a feature in the back of Diller’s Newsweek, the one with the “Muslim Rage” headline, not exactly a great lead-in to her sweet and fuzzy story about her daughter Tracy.

“I have no control over [the cover],” she said. She was more upset over who didn’t show up to the Peggy Siegal Co. book release. “Cindy didn’t come,” she said of Cindy Williams, her former “Laverne & Shirley” costar. “No one’s in town.”
