Finalists La'Porsha Renae and Trent Harmon are still waiting the hear which one of them will be the last American Idol, and while it's impossible to say who will win for sure, Clarkson has made her alliance known.
"I have never voted for anyone on @AmericanIdol not even for myself but I will be voting for @laporsharenae tonight," Clarkson tweeted on Wednesday. "I need her future record!"
Clarkson will be performing on the star-studded finale, which will also include numbers by Sparks, Aiken, Carrie Underwood, Ruben Studdard, Fantasia, Taylor Hicks, Diana DeGarmo, Danny Gokey, Bo Bice, Pia Toscano, Sanjaya, David Archuleta, Katharine McPhee, Kellie Pickler, Justin Guarini, Kimberley Locke, Kris Allen, William Hung, and more.
Former judge Kara DioGuardi is also returning to the Idol stage, this time as a performer, and she shared of photo of herself backstage with Idol musical directors.
Hung will dust off his vocal chords after switching careers. Following the release of his three albums, Inspiration, Hung for the Holidays and Miracle: Happy Summer from William Hung, in 2004 and 2005, Hung retired from music in 2011 and now works as a technical crime analyst for the Los Angeles Sheriff’s Department, according to On Air With Ryan Seacrest.
"This guy is back!" Gokey captioned an Instagram shot showing him with his arm around Hung. "Can anyone remember who this is?"
Season one runner-up Guarini took a trip down memory lane while posing for selfies with young fans who remembered him from their childhood.
"One of them even told me that they were 3 when they watched me on idol...that would make her 18...I tried not to feel too old," Guarini wrote. "On the other hand, I'm happy any 18 year old knows who I am with so many distractions in the world! I'm a very lucky (young) man, and so blessed to be a part of television and pop culture history!"
Guarini also snapped a pic with fellow returning performers Sparks and Locke.
There has been speculation that Sparks might be planning a duet with Harry Connick Jr.
Allen, Lee DeWyze, Phillip Phillips, David Cook and Nick Fradiani will use their stage time to honor the late David Bowie. Allen gave fans a peak at their rehearsal on Wednesday.
