All signs are pointing to Khloe Kardashian as the new host of The X Factor, newly made-over by creator Simon Cowell with Britney Spears and Demi Lovato at the judges' table. So says TMZ, which reported Friday that Kardashian -- known as the funny one among her reality-famous siblings -- is the frontrunner to get the gig following a successful screen test. If Cowell, who apparently considers her a magnet for young viewers along with Spears and Lovato, hires the E! star for his Fox talent competition, then she would basicaly have to start right away. The second-season reboot of X Factor premieres Sept. 12 and 13.
