‘X Factor’ First Live Show Bumped Up After Early World Series Win

Thanks to San Francisco's sweep of Detroit, the debut of Mario Lopez and Khloe Kardashian as "X Factor" hosts is coming early

Major League Baseball has once again shaken up the schedule for "The X Factor."

Fox's singing competition will hold its first live show of the season early, due to the early wrap-up of the 2012 World Series, which saw the San Francisco Giants sweep the Detroit Tigers four games to zero.

The first live show of the season will now air Oct. 31. It will be a special two-hour, seven-minute episode that will begin at 8 p.m. ET. It will air at 8 PT on a tape delay.

The scheduling change also means that new hosts Khloe Kardashian and Mario Lopez will be making their debuts earlier than expected. They will replace "X Factor" host Steve Jones with the Oct. 31 episode. Jones was ousted after the first season.

Thursday's episode will feature the reveal of the top finalists, with the audience voting on the finalists next week.

Earlier this month, a rain delay of the National League Championship created chaos for Fox's schedule. After originally hearing that the delay was likely to continue past primetime, Fox began airing "The X Factor," but when the delay was canceled about an hour later, the network pulled back "The X Factor" feed to switch to the game. However, a delay in the switch also caused "The Mindy Show" to briefly air for some viewers.
