Fox News may have a new rising star in their prime time line-up. Megyn Kelly, a transplant from the channel's daytime line-up, topped Bill O'Reilly's ratings on the second night of her show this week.

The Fox host’s new show “The Kelly File” debuted on Monday night and easily surpassed its rivals on MSNBC and CNN in total viewers.

The Hollywood Reporter's Live Feed said, “Chalk it up to the benefits of exposure or the unpredictable nature of cable news, but Fox News Channel's 'The Kelly File' more than doubled its demo haul on its second night.”

"Megyn Kelly's new prime-time show jumped 38 percent with total viewers to 2.8 million and a whopping 116 percent among adults 25-54 to 623,000. The numbers not only bested combined competition from CNN's Piers Morgan and MSNBC's Rachel Maddow, Kelly also scored the rare distinction of topping lead-in and reigning cable news champ Bill O'Reilly in the key demographic -- by about 45,000 viewers."

Kelly took over Sean Hannity’s 9PM Eastern prime slot with her new show which debuted last Monday night on the Fox News Channel.

Speaking about her new show last week Kelly said she was “not going to be the female Bill O'Reilly.'

She added: “It’s going to be a live broadcast... a breaking news program, not an opinion program.”
