Fox's Megyn Kelly makes surprise visit to CNN DNC party

Fox news host Megyn Kelly looks on during the Republican Presidential debate sponsored by Fox News at the Iowa Events Center in Des Moines, Iowa on January 28, 2016.

As the New York Times notes, Fox News anchor Megyn Kelly had not been seen in Philadelphia outside her network's compound at the Democratic National Convention all week.

That is until early Thursday, when she turned up at the CNN Grill at the Victory Beer Hall at XFINITY Live!.

The sighting, of course, set tongues wagging.

In a tweet, she said she went with fellow Foxer Dana Perino to the get together on a challenge from CNN anchor Don Lemon.

The Times says the visit indicates a cultural shift might be under way at Fox.

“In a way, the appearance of Ms. Kelly, who was joined by her fellow Fox host Dana Perino, signaled how much has changed at Fox since its chairman, Roger Ailes, was deposed. Fox personalities rarely fraternized with rival networks. (Greta Van Susteren was spotted at the grill this week, too.),"  so the Times said.
