"We're really good friends," Kidman explained. "I just did not feel his hand on my back."
The interaction -- which came after Bohemian Rhapsody won for Best Picture at the Golden Globes last Sunday -- seemed to show Malek trying to say hello to Kidman while everyone was taking the stage, but she appeared to brush him off.
Kidman said she was "mortified" by the accidental snubbing.
"I love that man. He's so gentle and softly spoken. He's a darling," Kidman gushed, adding that they were "both in a bit of a daze" at the time of the incident.
She added that they connected soon after the Globes to joke about what happened. "He sent me an email. I sent him an email... we were laughing, actually," Kidman shared.
"She's been a friend for a long time, and that's why the whole thing I find absolutely ridiculous and hilarious," he said. "But I'm having a laugh about it all."
"I got up there, and I was in such a daze I don't even know how I put together a collection of words that sounded coherent," the 37-year-old actor added. “So the fact that I knew Nicole [was there], I was like, 'Oh, here's a bit of safety.' And then she just didn't see me. It was as simple as that."
