'X Factor' Officially Signs Two New Co-Hosts TMZ

"The X Factor" has officially signed two familiar television personalities as its new co-hosts, reports. The Fox singing competition signed Mario Lopez and Khloe Kardashian, the story reports.

Both have signed their contracts after being close to deals for months, the story notes. They will replace former host Steve Jones, who got the boot in a housecleaning last winter by show creator Simon Cowell, as previously reported.

The salaries of Kardashian and Lopez are expected to add millions to the show's budget, although the story doesn't disclose how much either will be paid. The pair will debut in November.
