'X Factor' Gets S3
FOX renews the talent competition for a third season.
Prepare to be seeing a lot more of Mario Lopez.

The Hollywood hunk will now be appearing on TV live thanks to his new co-hosting gig on FOX’s The X Factor.

Along with Keeping Up With the Kardashians star Khloe Kardashian, 28, the 39-year-old will be kicking off the singing competition’s series of live shows this Wednesday.

Originally slated to air on Thursday night, the shows were bumped up and back to their original Wednesday-Thursday schedule due to the quick World Series sweep by the San Francisco Giants.

So what can fans expect this week?

Aside from Lopez’s super hot bod and million dollar smile gracing their TV sets, the show’s Top 16 acts will perform live on a special two-hour episode.

Of course, judges Simon Cowell, Demi Lovato, Britney Spears and L.A. Reid will also make appearances to mentor their singing hopefuls. The chosen top finalists will be revealed on Thursday at 8 PM.

For now, get to know X Factor’s newest host and relive Lopez’s hottest moments in the gallery — above.
