Megyn Kelly went scorched earth on Doug Emhoff’s ex-wife, Kerstin Emhoff, in a fiery online spat, claiming Kerstin wasn’t “sexy enough” to keep her husband from “sleeping with the nanny.” The shocking personal insults between the two blondes erupted after Kerstin, a Hollywood producer and mother of Emhoff’s two children, criticized Kelly for disparaging Jennifer Lopez’s recent sexually charged performances.

On her podcast, Kelly had slammed the pop icon, saying Lopez, 55, had crossed the line into “soft porn” and was no longer a sex symbol. “We’re not sex symbols,” Kelly declared. “That ship has sailed — it sailed with menopause.”

Kerstin Emhoff fired back on social media (without tagging Kelly directly), writing, “I bet tons of people look at J.Lo and want to have sex with her. Megan [sic] — if you actually think that post-menopausal women can’t be sexual, you are missing out. You can close up your 55-year-old shop while the rest of us are open for business.”

Kelly exploded in response, dragging up a long-rumored affair between Doug Emhoff and their children’s nanny, Najen Naylor. The nanny, a blonde teaching assistant at their kids’ elite Los Angeles private school, allegedly had an affair with Doug that led to a pregnancy and the end of his 16-year marriage to Kerstin in 2009.

“You were too chicken s*** to actually cc me on your post,” Kelly wrote, “but let’s just say I’m sexy enough to keep my husband from sleeping with the nanny. Unlike J-Lo, however, I don’t feel the need to fake hump a bunch of strangers to prove I’ve still got it.”

Kerstin quickly replied, insisting she wasn’t hiding. “I’m definitely not a chicken s*** @megynkelly. I assumed you would see it,” she wrote. She accused Kelly of attacking J.Lo for her age and chastised her for dragging up private marital matters she doesn’t know about. “I choose to support women. Try it,” Kerstin added.

But Kelly was relentless. “Actually, I have an excellent idea that you married a guy who was a total s***,” she retorted. “And now you’re telling the internet you’re ‘open for business’ — so good luck with that.”

The clash started after Kelly criticized Lopez’s suggestive dance moves on her podcast, accusing the star of simulating explicit sex acts and saying, “She’s 55 years old and hasn’t come to grips with the fact that she’s not a sex symbol anymore.”

The personal feud quickly spilled into a wider culture war, with the messy details of Doug Emhoff’s affair becoming part of the public record. Doug and Kerstin ended their 16-year marriage in 2009 when she discovered the affair, sources said. Their daughter Ella was 10 and son Cole was 15 at the time.

Najen Naylor, the nanny-turned-teacher at the children’s private school, was reportedly pregnant during the affair, though it’s unclear what happened to the child. After the scandal, Naylor left the school, became a director at Audible, and now lives quietly with her family.

Kerstin Emhoff has mostly stayed silent about the cheating rumors, refusing comment when contacted by the press. However, her sudden defense of Jennifer Lopez and attack on Megyn Kelly dragged these old skeletons back into the spotlight, sparking one of the most heated celebrity Twitter battles in recent memory.
