TV Guide Channel wants to make sure American Idol fans who just can't get enough of the show are satisfied.

The network will launch a second season of Idol Tonight, the live preshow for Fox's Idol, in March, at 8 p.m. Wednesdays, after the contestants have been whittled down to 12 finalists.

Idol Tonight features interviews with former finalists, industry insiders, fashion stylists and vocal coaches, among others.

Justin Guarini (pictured), runner-up on the first season of American Idol, will co-host with Season 3 finalist Kimberly Caldwell and Rosanna Tavarez, one of the winners of WB Network's "Popstars."

TV Guide Channel president Ryan O'Hara said Idol Tonight is one of the network's highest-rated regular series.

"American Idol is like the Super Bowl week in and week out, and our fans can't get enough of it," he said. "We're positioning ourselves as a destination for all things American Idol."

O'Hara added that because Idol Tonight airs from the CBS Television City studios in Los Angeles - from where American Idol six is also broadcast - "there's all the energy and excitement from the fans and contestants. It's the ultimate pregame show."
