Idol Gives Back brought out quite the crowd from all different areas of the entertainment industry for the taping in Hollywood last night. Reese and Brad shared their pretty faces with the audience, while Mariah and Miley were among the musical performers of the night. Teri showed off her pipes (even though most of you wish she wouldn't) and Fergie took the stage to do a song with Heart. As for the theme of the night, Carrie Underwood summed it up nicely, saying, "It's not about self-promoting. It's not about singing your latest single. It's not about trying to be the most-downloaded whatever on iTunes. It's all about getting people to call in and do something." The charitable special airs this Wednesday, and we can't wait to check out the wonderful edition of one of our favorite shows.
