Molly Ringwald conceived daughter Mathilda in a Studio 54 dressing room at the end of her “Cabaret” run

What good is schtupping in your dressing room — come, hear the music play...

Molly Ringwald has had a number of iconic moments in her life, mostly on camera, but in a new interview with The Times, Ringwald reveals an iconic private moment that finally realized her dream of motherhood.

"I believe that Mathilda was conceived in the dressing room at Studio 54 right at the end of my run playing Sally Bowles in Cabaret in 2003," Ringwald recalled. "It’s so Mathilda to be conceived in such an iconic place."

The Feud: Capote vs. the Swans actress goes on to explain that she "always knew" she wanted kids but it took her till she was 36 to conceive. "At that age the biological clock is a real thing and it had kind of become deafening," she noted. "All I could think about was: must have kids."

And with that clock tick-tick-ticking in her ear, why not a dressing room where Liza Minnelli herself, the original Sally Bowles, may have powdered her nose — one way or another.

Ringwald and husband  Panio Gianopoulos would later add to their family with the birth of twins Roman and Adele, now 14. Mathilda, 20, is currently following in her mother's footsteps, with an upcoming role in Michael Showalter's film, The Idea of You, starring Anne Hathaway.

As for the ever-present specter of the "nepo baby" label, Ringwald calls it "ridiculous."

"Of course if you have a parent in the industry, it’s something that you’ve heard about and might be genetically predisposed to," she remarked. "We wouldn’t let Mathilda pursue acting when she was a child, as we wanted her to concentrate on being a kid. She fought us on that — she’s still kind of mad about it, but it was the right decision."

She added, "I don’t think that professional acting is a great way for kids to grow up."
