Last year’s American Idol runner-up, Adam Lambert, will mentor this season’s remaining eight contestants next Tuesday. “It’s true!” he wrote on Twitter. “In addition to performing on Idol April 14th, I will be mentoring the top 8 on the 13th. I feel honored to be asked. Even though I’m just at the start of my recording career, I hope to lend some insight as one who’s been thru the Idol adventure. Excited!!” This is the first time an American Idol alumnus has been asked to mentor. Adam will perform his hit single “Whataya Want from Me,” which is currently No. 20 on Billboard’s Hot 100, on the results show the following night. This year’s American Idol has feen featuring younger artists this season, including Miley Cyrus and Usher, and younger guest judges during the early auditions, such as Joe Jonas and Avril Lavigne. Lambert has promised that his appearance on the show will not be outrageous as his recent performances have been, tweeting, “Don’t worry America: I will be beyond family friendly. Relax and enjoy. For Your Entertainment.” ~Alexandra Heilbron
