After mentoring "American Idol" participants during the Elvis Presley week, Adam Lambert went to the reality singing show on April 14 to make a live performance. Wearing a suit, he treated viewers with "Whataya Want From Me", a single which appears in his debut album "For Your Entertainment".
Prior to Adam Lambert's performance, Justin Gaston took the stage, making a duet with Brooke White. While the ex-boyfriend of Disney songstress Miley Cyrus brought his guitar, the former contestant of "Idol" season 7 sat behind a grand piano. They delivered "If I Can Dream".
Two people, Andrew Garcia and Katie Stevens, have left the competition this week. The remaining contestants reportedly will be mentored by Alicia Keys for Idol Gives Back week. On Wednesday, April 21, Carrie Underwood, Black Eyed Peas, Annie Lennox, Jeff Beck and Sir Elton John will make two-hour special performances for the charity effort.
