Sean "Diddy" Combs attends TimesTalks Presents: An Evening with Sean "Diddy" Combs at The New School on September 20, 2017 in New York City.

The witness stand in Sean "Diddy" Combs' federal case has become a source of bombshell revelations—and it seems no one is holding back.

Allegations and stories of uncomfortable encounters with the music mogul are emerging from every corner, and one of the voices joining the fray is American journalist Megyn Kelly, who shared that she personally witnessed an inappropriate moment involving Diddy and one of the Kardashian sisters.

Speaking on the podcast 'The Nerve with Maureen Callahan,' Kelly claimed she saw Diddy "rubbing up" against one of the Kardashians inside a bathroom at the Met Gala, the star-studded fashion event held each May at New York City's Metropolitan Museum of Art.

While Kelly did not specify which Kardashian sister was involved, social media users quickly jumped into detective mode. Soon, a widely circulated photo from 2017 resurfaced showing Diddy alongside Kim Kardashian, Kendall Jenner, Kylie Jenner, A$AP Rocky, Willow Smith, and Captain Marvel star Brie Larson—all present at the same Met Gala event.

The story came about when Kelly recalled her time at the Met Gala in 2016 and 2017. "What I remember most was P. Diddy being all comfy in the Met bathroom. It was the ladies' bathroom, so I was in there... (he was) rubbing up against a Kardashian," she said.

The couple wasn't alone, according to Kelly. "There were other Kardashians and other idiot models—not the supermodels we all grew up with, but others, the influencers. Everyone was in there. No one was using the bathroom. They were smoking and making out. That was P. Diddy, kind of gross," she added.

It's worth noting that just because Megyn Kelly says she was a Kardashian doesn't necessarily mean she was Kim Kardashian, the only one with that last name in the now infamous bathroom photo. For many people, the term "Kardashian" also encompasses her younger sisters, who bear their father's last name, now named Caitlyn Jenner.

In 2017, Kim was married to Kanye West, who also attended that Met Gala. Considering everything we know now about Diddy, Kelly's story doesn't sound far-fetched. It's worth noting that at the time, Kendall was 21 and Kylie was 19.
