Shocking ‘Babygirl’ milk scene with Nicole Kidman really happened to director: ‘Incredible, hot’

In the new movie “Babygirl,” Nicole Kidman gets down and dairy. 

During a steamy bar scene that’s become a talker online, her New York CEO character Romy is sent a glass of milk by the young intern she’s having an affair with played by 28-year-old Harris Dickinson (“Triangle of Sadness”). 

And, in a kinky moment, she’s forced to drink it.

Weird, but true. Writer-director Halina Reijn admitted in an interview this week that she once really had a similar Vitamin-D dalliance that she based the sexy encounter on. 

“It happened to me,” Reijn, 49, told IndieWire. 

“I was playing in Belgium onstage, and I got offstage, and I had a really good run, and I was like, ‘Oh my god!’ I felt really good about myself for one night in my life. All my colleagues were like, ‘No, we’re going to bed.’ They’re all boring. I was all alone.” 

She added: “I went to a bar, and I ordered something boring like a Diet Coke because I didn’t drink at that time because I was a control freak. There was this young Belgian actor — I can’t say who it is — but he was famous. I knew of him. I’d never spoken to him. He was at least 15 years younger than I, and he ordered me a glass of milk.”

“I thought it was an incredible, hot thing to do, and so courageous, and so I wanted to reward him by drinking the whole thing, and I did. It did make me a little nauseated, to be honest with you, because it was cow milk. It was back in the day.”

Although the pair got milk, they didn’t leave together. But Reijn called the interaction “one of the most arousing moments of my life.”

In a four-star review, The Post called “Babygirl,” which also stars Antonio Banderas, “a captivating psychological drama,” adding that “rarely is that workplace taboo as scintillating.”

Awards voting bodies have agreed. Kidman, 57, is nominated for a Golden Globe on Sunday night for best actress in a motion picture – drama.
