(FORTUNE) — Megyn Kelly, the Fox News anchor who is giving Bill O’Reilly and other TV news stalwarts a run for their money, is on the cover of this Sunday’s New York Times Magazine. And the story about Kelly inside includes a telling anecdote about her husband, Doug Brunt, coming to recognize her meteoric power. Here’s an excerpt:
Brunt said the most stirring moment came in October, when Kelly was hosting her show from the oceanside in Dana Point, Calif., where she was attending Fortune magazine’s Most Powerful Women Summit. Unexpectedly, an enormous crowd began to gather. “It was one of those moments when you see how big it has become,” Brunt said.
What happened inside the conference, which was a gathering of the most powerful women in business, was no less extraordinary. Sheryl Sandberg, the chief operating officer of Facebook FB 0.61% , who wrote Lean In, was to interview Kelly on the main stage. Sandberg introduced Kelly with a clip from a celebrated Megyn moment from 2013, in which she challenged the conservative commentator Erick Erickson for saying that the national increase in female breadwinners ran counter to the biologically determined order. “Who died and made you scientist in chief?” Kelly asked him.

The conference hall erupted in cheers, and Sandberg herself, who worked in the Clinton administration before her hiring at Facebook, audibly whooped. “I saw that on TV,” she told the crowd, “and I just cold-called her and said ‘I love you, you are awesome.’ ”
