It’s official: Khloe Kardashian and Mario Lopez will join Britney Spears, L.A. Reid, Demi Lovato and Simon Cowell in November as hosts of Fox’s flagship singing talent show, reports The New York Daily News.

"The worst kept secret in Hollywood is out," Simon Cowell said in a statement. "Mario and Khloé are our hosts. They will debut on our first live show in November and I couldn't be happier." Lopez, 39, has experience hosting “Extra,” and Kardashian is used to being in front of the camera from her E! reality series, “Keeping Up With the Kardashians.” They replace the Welsh presenter Steve Jones, who made his name in the U.K on Channel 4 hosting their youthful T4 franchise. “We have to find people who have a great chemistry, but Khloe is definitely up there in running,” Cowell told Ellen DeGeneres last month.

Kardashian proved to be a tough cookie when it came to negotiations. Talks with the star reached a tense point when an argument over her being on two networks at once arose. However, her determined nature made the deal happen, and she can now enjoy being part of the biggest talent show on TV (once it starts beating The Voice for ratings, that is).
