Mariah Carey, Adam Lambert, PSY To Perform On ‘American Idol’ Finale

By: Sam Lansky / May 16, 2013

Well, it’s been a long, bleary season of American Idol, but at last, tonight’s finale is upon us, and the show gets to do what it does best: Promote its own! Yes, the show’s resident diva Mariah Carey will be performing her still-astonishingly-good new single “#Beautiful” (hashtag beautiful) as part of a medley of her greatest hits including “Vision of Love,” “Make It Happen,” “We Belong Together,” “My All” and “Hero.” Randy Jackson will be on bass, and she’ll be backed by a full gospel choir, so it sounds like the performance will be very relaxed and mellow and not at all self-congratulatory. (Then again, if anyone deserves that level of pomp and circumstance, it’s definitely Mariah Carey, right?)

Also! Glittery pop prince Adam Lambert will be returning to the Idol stage (to duet with Angie Miller), and — presumably because Scooter Braun has compromising photos of Ryan Seacrest that he’s using to blackmail him, because there’s literally no other reason I can imagine why this would be happening — novelty K-pop act PSY will be performing his new single, “Gentleman.”

It’s going to be a long night, folks.
