And Season 11 finalist Colton Dixon will also take the stage to perform his new single, "Love Has Come For Me." Talk about a night full of amazing performances!
Colton has had quite a bit of success since Idol, as his debut album hit number 15 on the charts in January. We’re sure Angela Miller will be excited to see him perform, since Angie performed his “Never Gone” recently.
However, the performance we're most looking forward to is Keith's. The country singer has proven to be an amazing judge, and now we can't wait to hear his wonderful voice on the show.
We have yet to find out what Keith will be performing, but he certainly has plenty of hits to choose from. He has had 14 number-one songs, such as his recent hits from his 2010 album, including "You Gonna Fly," "Long Hot Summer," and "Without You," which all hit number one.
So which tune will he go with? The suspense is killing us.
We can imagine Keith's performance will be especially thrilling and beneficial for the show's current country performers, like Janelle Arthur and Kree Harrison.
Meanwhile, Katharine McPhee has certainly been busy since competing on Idol. She now stars on the NBC musical series Smash.
Then again, it's not like we really needed another reason to get excited for this week's results show, since we'll be finding out which of the Top 8 will be sent packing. Can't wait!
