With American Idol‘s big Wednesday event, “Idol Gives Back,” you’d think that Ryan Seacrest would be in top hosting form. Turns out, Ellen DeGeneres will be hosting the high-profile gig from the Walt Disney Concert Hall in Los Angeles. Check in on Wednesday night from 8:00 - 10:00 to see such big names as Kelly Clarkson, Carrie Underwood, Gwen Stefani, Celine Dion, Hugh Grant, Jack Black, and more. And of course, all of this is a big telethon to raise funds for the poverty-stricken in Africa and America. Gotta hand it to Idol, this could really rake in some big money. The “Idol Gives Back” performance show is on Tuesday, with the final six duking it out in a “life anthem” theme. When vieweres vote, corporate sponsors will donate money on voters’ behalf. Never fear, Seacrest will be taking care of things from the usual location, with DeGeneres holding down the fort at the Disney Concert Hall.
