News anchor Megyn Kelly will move to FOX News Channel's primetime lineup upon her return from maternity leave, announced Roger Ailes, chairman and CEO of the news station.

Kelly, already a mother of a son named Yates and daughter Yardley, is on her third maternity leave from FOX News' America Live. She exited the show on Wednesday by playing memorable moments and highlights from over the past three years of being an anchor. After the show she posted a picture on Twitter of her last day working at American Live. Co-workers threw Kelly a farewell party that included pizza, sweets and Pellegrino. In the picture Kelly appears very happy and very pregnant in her magenta maternity dress.

Her maturinity leave began on the Fourth of July.

"Roger Ailes hired me nine years ago when I was new to this business and he had little other than instinct to suggest it might work out. I was grateful to him then, remain so today, and am excited for this next opportunity," Kelly told Deadline.

Since February 2010, the 42-year-old has anchored the network's daytime news program. At the same time she was on a weekly primetime segment on The O'Reilly Factor titled The Kelly File.

Last fall she co-anchored FOX News Channel's 2012 election night coverage alongside Bret Baier, which delivered more than 12 million viewers and finished second among all of the broadcast and cable networks. Kelly also co-anchored Fox News Channel's primetime coverage of the Republican and Democratic conventions live from Tampa, Fla. and Charlotte, N.C. Prior to that, she co-anchored the network's 2012 coverage of the presidential primaries and moderated two GOP presidential debates.

In addition to her primetime promotion, the network signed long-term deals with Bret Baier, Shepard Smith, Bill O'Reilly, Sean Hannity and Greta Van Susteren.
