The TV Zone

Here's big news in the TV tab world: Mario Lopez will become the new host of "Extra" this fall. He's a better dancer than outgoing Mark McGrath, and -- I'm assuming -- he's better ratings bait than his soon-to-be-predecessor as well. (Mario's been on the show for a while, anyway -- weekends, I think -- so this isn't that big 'o surprise...)

Meanwhile, the five Emmy-nominated hosts of the five biggie reality shows will host this September's rilly big Emmycast....WhooPEE!! (Now I'm really gonna watch...). They are...Tom Bergeron (“Dancing with the Stars”), Heidi Klum (“Project Runway”), Howie Mandel (“Deal or No Deal”), Jeff Probst (“Survivor”) and Ryan Seacrest (“American Idol”).

I'm assuming, though, that Ry is day to day because of the shark attack.
