The verdict: We can’t help but think that several years ago, the “punk” Avril Lavigne would have sneered at a show like “American Idol.” But she’ll be part of the machine during the Los Angeles round of auditions.
The verdict: The pint-sized “Pushing Daisies” star and Tony winner has vocal chops to spare. She might also be even nicer to the contestants than Paula was, if that’s possible. (ABC)
‘Idol’ connection: Was in the audience for a semifinal performance episode last season.
The verdict: We know the “How I Met Your Mother” star and Tony/Emmy host can sing -- but we’d be more interested in seeing if he can bring the funny to the sometimes-tedious audition episodes. (Wire Image)
‘Idol’ connection: Performed on last season’s top three results show.
The verdict: Wore a cape with “Adam Lambert” on it for her performance; such obvious bias might not play at the judging table. (Wire Image)
‘Idol’ connection: Performed on the one-off “World Idol” in 2003; “Idol” creator Simon Fuller was manager of the Spice Girls.
The verdict: Though some leaked reviews of her guest stint were not good, we’re looking forward to her haughtily dismissing untalented hopefuls. (Wire Image)
‘Idol’ connection: Performed on the show’s 2006 finale; countless contestants have been told to be more like her.
The verdict: If anyone can give advice on having a big, contemporary R&B sound, it’s her. (Wire Image)
‘Idol’ connection: None.
The verdict: Twain has been somewhat off the radar in recent years. Would she help the show more than the show helps her? (Wire Image)
‘Idol’ connection: None, save for the fact that a sizable portion of the show’s audience looooves him.
The verdict: He’s shown a likable self-deprecating streak in stunts like this -- but we suspect Simon Cowell might eat him alive. (Disney Channel)
