NEW YORK (CBSNewYork) – CBS announced Monday Fox News’ Megyn Kelly will be a guest on next Sunday’s post-Super Bowl show. Tina Fey, Will Ferrell, Margot Robbie and comedy duo Key and Peele will also be on the show.

Kelly has been in Donald Trump’s cross-hairs since the first Republican presidential debate when she questioned the billionaire’s previous comments about women. Trump skipped out on last week’s debate because Kelly was one of the moderators.

Colbert told AdWeek that they’re expecting 10 times their normal audience for next Sunday’s show.

“Doing a show for 3 million people or doing the show for 25 million people, we can’t feel the difference—it’s doing it live that’s the difference. We did one just for schnicks [last month] because no one had ever done ‘The Late Show’ live,” Colbert said. “The energy is fantastic. If I didn’t have to stay up until 11:35 to do it, I would do it every day. Now we’re doing the show absolutely to the second, live to tape because we love that energy so much and don’t want to lose it.”

Colbert added that they will be writing the show during the game

“Everything’s about Super Bowl. We’ll do our live analysis, and we’ll have our live analysis of the most important thing: who won the commercials. And we’ll have our own Super Bowl commercial. We’ll be watching the game and writing the show as we go. We practiced doing the Patriots-Broncos because that’s something we’ve never done before. We’ve written jokes live about an election, but how do you write jokes about a Super Bowl? We’ve got to turn the jokes around in 20 minutes,” Colbert told AdWeek.

The hour-long show will air after the Super Bowl on Sunday, Feb. 7.
