Grown-Up Miley & Hudson Wow Idol Crowd

Adam Lambert might be leaps and bounds over fellow American Idol contestants, but the weekly influx of star power he shares the stage with must be keeping him a little humble.

Wednesday's episode was no different, as two of the brightest young stars in show business -- Jennifer Hudson and Miley Cyrus -- treated the audience to stellar performances during the show's Hollywood-themed week.

Cyrus, the recent target of a vicious Jamie Foxx diatribe (and subsequent apology), looked like a prom queen in her lavender dress while performing her song, The Climb. The second-generation entertainer's film, Hannah Montana: The Movie, is currently the top-earning film in the country.

Hudson, whose humble beginnings as an Idol contestant eventually vaunted to elite levels of Oscar- and Grammy-winning triumph, displayed her soulful talents with a rendition of her single If This Isn't Love.
