Score another X for the Kardashian sisters!
Kim Kardashian's fame was launched by an X-rated sex tape. Now sister Khloe Kardashian can add an X to her resume: She's just been named as a co-host of Fox's "The X-Factor."
Khloe Kardashian and former "Saved by the Bell" star Mario Lopez will join forces as the hosts of the Fox singing competition when live shows start airing in November.
"The worst-kept secret in Hollywood is out," said "X Factor" creator Simon Cowell. "Mario and Khloe are our hosts ... and I couldn't be happier."
