As if One Direction, Adele and Coldplay weren't enough, we've now learned that former winners Little Mix will be returning to the stage alongside last year's runner-up Fleur East.
How amazing does that sound?!
There's no word yet on what Perrie, Jade, Jesy and Leigh-Anne will be performing with Fleur but you already know it's going to be pretty girl power spectacular, right?!
Little Mix - who were the first and only group to win the show when they triumphed in 2011 - will perform with Fleur at this weekend's big finale at Wembley, taking to the stage during the Saturday live show.
We'll also see last year's winner Ben Haenow returning with 2006 winner Leona Lewis for a duet.
Ah we're so excited!
And we haven't even learned yet who the superstar guests are who will be duetting with the finalists, although we're guessing Rita Ora may join her act Louisa Johnson on stage…
