 On the seventh season of the talent competition American Idol , Carey was featured as a mentor for the top @-@ seven week . Titled " Mariah Carey Week " and airing live on April 14 , 2008 , the contestants were to perform a song from the singer 's catalog . After all seven contestants sang their individual songs , they all came together for a live rendition of Carey 's 1996 collaboration with Boyz II Men , " One Sweet Day " . Overall , critics noted how a Carey themed week would be extremely difficult for the performers , due to their vocally strenuous nature . Following their joint performance , Carey emerged onto the stage and performed " Bye Bye " live , while backed by a trio of supporting vocalists . Tamara Jones of The Washington Post jokingly commented on Carey 's flailing hand movements during the performance , writing how she was " waving like a malevolent homecoming queen " . Gil Kaufman from MTV News complimented Carey 's performance , commenting on her " barely there micro @-@ dress " and writing how she " serenaded the audience with her homage to lost ones . " The Calgary Sun 's Lindsey Ward described it as a " less @-@ than @-@ fab performance " , although complimenting on Carey 's leaner figure , " Oh , who am I kidding ? She would look hot in a paper bag . " On April 25 , 2008 , Carey opened the Good Morning America " Summer Concert Series " with a live performance in Times Square . Carey , wearing a pink mini @-@ skirt , began the set with " Touch My Body " in front of thousands of fans . During the song , her backing vocals began to malfunction , causing it to repeat phrases and play during her main vocal moments . In order to let the sound engineer know of the problem , she substituted part of the lyrics for " stop singing my part now baby " , and completed the final chorus . She continued on with " I 'm That Chick " , and completed the three @-@ song set @-@ list with her follow @-@ up single , " Bye Bye " . After marking the album 's stateside launch with her appearance on Good Morning America , Carey took to Europe to perform on several programs . She began with an interview on the British radio station , BBC Radio 1 , and continued onto a live rendition of " Touch My Body " on both The Sunday Night Project and The Paul O 'Grady Show .
