(TMZ) - It's official, Khloe Kardashian and Mario Lopez will be the new co-hosts of "X Factor," TMZ has confirmed with sources connected to the show. 

TMZ broke the story that Khloe and Mario had been very close to a deal for months, but now has confirmed they've both signed on the dotted line, and it's a done deal. 

TMZ reports that the duo's salaries will add millions to the budget, on top of an already enormous talent budget, with Britney Spears in the lead at $15 mil. 

K&M are expected to debut on the show in November.
