Demi Lovato has officially signed a deal with X Factor, just like Britney Spears did not long ago. Popcrush reports that Lovato's paycheck isn't known yet as to whereas Spears' landed on a whopping $15 million.
The tv-show will apparently not interfere with Lovato's upcoming summer tour. The official announcement will come at the Fox Upfronts where both Spears and Lovato will announce their participation in the show.
